' -and -.RB ` [ '. -Care must be taken to quote meta-characters appropriately from the shell. -File permissions are set to those in the archive; -if the caller is the super-user, -ownerships are restored as well. -.I Cpio -will not create directories, -preserve modification times -or overwrite more recently modified target files -unless the appropriate -.IR \-d , -.I \-m -or -.I \-u -options are specified. -Archives compressed with -.IR bzip2 (1), -.IR compress (1), -.IR gzip (1), -or -.IR rpm (1) -are transparently de\%compressed on input. -.PP -With -.BR \-o , -.I cpio -works in -.RI ` copy-out ' -mode, -creates archives -and writes them to standard output per default. -A list of filenames to be included in the archive is -read from standard input; -if the name of a directory

files -(see also its -.I \-cpio -and -.I \-ncpio -operators). -When producing a filename list for -.IR cpio , -find should always be invoked with -.I \-depth -since this makes it possible to extract write-protected directories -for users other than the super-user. -.PP -The -.B \-p -option selects -.RI ` pass ' -mode; -a list of files is read from standard input as described for -.IR \-o ; -files are copied to the specified -.IR directory , -preserving attributes as described for -.IR \-i . -Special files are re-created in the target hierarchy, -and hard links between copied files are preserved. -.PP -When a premature end-of-file is detected with -.I \-i -and -.I \-o -and the archive is a block or character special file, -the user is prompted for new media. -.PP -The following

the archive is created. -Unlike some other implementations, -.I cpio -fully supports -archives of either byte order. -.I \-H\ bbs -can be used to create an archive -with the byte order opposed to that of the current machine. -.PP -The -.B sgi -format extends the binary format -to handle larger files and more device bits. -If an archive does not contain any entries -that actually need the extensions, -it is identical to a binary archive. -.I \-H\ sgi -archives are always created in MSB order. -.PP -The -.B odc -format was introduced with System\ III -and standardized with IEEE Std. 1003.1. -All known -.I cpio -implementations since around 1980 can read this format. -.PP -The -.B dec -format extends the -.I odc -format -to support more device bits. -Archives in this format are generally incompatible with -.I odc -archives -and need special implementation support to be read. -.PP -The -.B \-c -format was introduced with System\ V Release\ 4. -Except for the file size, -it imposes no practical limitations -on files archived. -The original SVR4 implementation -stores the contents of hard linked files -only once and with the last archived link. -This -.I cpio -ensures compatibility with SVR4. -With archives created by implementations that employ other methods -for storing hard linked files, -each file is extracted as a single link, -and some of these files may be empty. -Implementations that expect methods other than the original SVR4 one -may extract no data for hard linked files at all. -.PP -The -.B crc -format is essentially the same as the -.I \-c -format -but adds a simple checksum (not a CRC, despite its name) -for the data of regular files. -The checksum requires the implementation to read each file twice, -which can considerably increase running time and system overhead. -As not all implementations claiming to support this format -handle the checksum correctly, -it is of limited use. -.PP -The -.B sco -and -.B scocrc -formats are variants of the -.I \-c -and -.I \-H\ crc -formats, respectively, -with extensions to support larger files. -The extensions result in a different archive format -only if files larger than slightly below 2\ GB occur. -.PP -The -.B cray -format extends all header fields to 64 bits. -It thus imposes no practical limitations of any kind -on archived files, -but requires special implementation support -to be read. -Although it is originally a binary format, -the byte order is always MSB as on Cray machines. -The -.B cray5 -format is an older variant -that was used with UNICOS 5 and earlier. -.PP -The -.B otar -format was introduced with the Unix 7th Edition -.I tar -utility. -Archives in this format -can be read on all Unix systems since about 1980. -It can only hold regular files -(and, on more recent systems, symbolic links). -For file names that contain characters with the most significant bit set -(non-ASCII characters), -implementations differ in the interpretation of the header checksum. -.PP -The -.B ustar -format was introduced with IEEE Std. 1003.1. -It extends the old -.I tar -format -with support for directories, device files, -and longer file names. -Pathnames of single-linked files can consist of up to 256 characters, -dependent on the position of slashes. -Files with multiple links can only be archived -if the first link encountered is no longer than 100 characters. -Due to implementation errors, -file names longer than 99 characters -can not considered to be generally portable. -Another addition of the -.I ustar -format -are fields for the symbolic user and group IDs. -These fields are created by -.IR cpio , -but ignored when reading such archives. -.PP -With -.BR "\-H tar" , -a variant of the -.I ustar -format is selected -which stores file type bits in the mode field -to work around common implementation problems. -These bits are ignored by -.I cpio -when reading archives. -.PP -The -.B pax -format is an extension to the -.I ustar -format. -If attributes cannot be archived with -.IR ustar , -an extended header is written. -Unless the size of an entry is greater than 8\ GB, -a -.I pax -archive should be readable by any implementation -capable of reading -.I ustar -archives, -although files may be extracted under wrong names -and extended headers may be extracted as separate files. -If a file name contains non-UTF-8 characters, -it may not be archived or extracted correctly -because of a problem of the -.I pax -format specification. -.PP -The -.B sun -format extends the -.I ustar -format similar as the -.I pax -format does. -The extended headers in -.I sun -format archives are not understood -by implementations that support only the -.I pax -format and vice-versa. -The -.I sun -format has also problems with non-UTF-8 characters in file names. -.PP -The -.B GNU -.I tar -format is mostly compatible with the other -.I tar -formats, -unless an archive entry actually uses its extended features. -There are no practical limitations on files archived with this format. -The implementation of -.I cpio -is limited to expanded numerical fields -and long file names; -in particular, -there is no support for sparse files or incremental backups. -If -.I cpio -creates a multi-volume -.I GNU -archive, -it just splits a single-volume archive in multiple parts, -as with the other formats; -.I GNU -multi-volume archives are not supported. -.PP -The -.B bar -format is similar to the -.I tar -format, but can store longer file names. -It requires special implementation support to be read. -.PP -The -.B zip -format can be read in many non-Unix environments. -There are several restrictions on archives -intended for data exchange: -only regular files should be stored; -file times, permissions and ownerships -might be ignored by other implementations; -there should be no more than 65536 files in the archive; -the total archive size should not exceed 2 GB; -only -.I deflate -compression should be used. -Otherwise, -.I cpio -stores all information available with other archive formats -in extended -.I zip -file headers, -so if archive portability is of no concern, -the -.I zip -implementation in -.I cpio -can archive complete Unix file hierarchies. -.I Cpio -supports the -.I zip64 -format extension for large files; -it automatically writes -.I zip64 -entries if necessary. -.I Cpio -can extract all known -.I zip -format compression codes. -It does not support -.I zip -encryption. -Multi-volume -.I zip -archives are created as splitted single-volume archives, -as with the other formats written by -.IR cpio ; -generic multi-volume -.I zip -archives are not supported. -.SH EXAMPLES -Extract all files named -.I Makefile -or -.I makefile -from the archive stored on -.IR

The only difference is in - * the c_filesize field: - * - * [first header: file size X times 2 GB] - * [first data part: X times 2 GB] - * [second header: file size modulo 2 GB] - * [second data part: rest of data] - * - * The first header can be recognized by a negative c_filesize. A - * value of 0xFFFFFFFF means that 2 GB follow, 0xFFFFFFFE -> 4 GB - * 0xFFFFFFFD -> 6 GB, 0xFFFFFFFC -> 8 GB, and so forth. The second - * is a standard binary cpio header, although the following data is - * meant to be appended to the preceding file. - * - * It is important to note that padding follows the number in - * c_filesize, not the amount of data written; thus all data parts - * with odd c_filesize fields (0xFFFFFFFF = 2+ GB, 0xFFFFFFFD = 6+ GB - * etc.) cause the following archive entries to be aligned on an odd - * offset. This seems to be an implementation artifact but has to be - * followed for compatibility. - * - * This extension seems a bit weird since no known cpio implementation - * is able to read these archive entries without special support. Thus - * a more straightforward extension (such as storing the size just past - * the file name) would well have had the same effect. Nevertheless, - * the cpio -K format is useful, so it is implemented here. - * - * --Note that IRIX 6.X tar also has a -K option. This option extends - * the tar format in essentially the same way as the second extension - * to cpio described above. Unfortunately, the result is definitively - * broken. Contrasting to the binary cpio format, the standard POSIX - * tar format is well able to hold files of size 0xFFFFFFFF and below - * in a regular manner. Thus, a tar -K archive entry is _exactly_ the - * same as two regular POSIX tar entries for the same file. And this - * situation even occurs on a regular basis with tar -r! For this - * reason, we do not implement the IRIX tar -K format and will probably - * never do so unless it is changed (the tar format really has a lot - * of options to indicate extensions that might be used for this). - * - * Many thanks to Sven Mascheck who made archiving tests on the IRIX - * machine. - */ -/* - * This function reads the second header of a SGI -K format archive. - */ -static void -readK2hdr(struct file *f) -{ - struct file n;

This compression - method searches for as much of the current string of bytes (up to a length - of ~320) in the previous 4K or 8K bytes. If it doesn't find any matches - (of at least length 2 or 3), it codes the next byte. Otherwise, it codes - the length of the matched string and its distance backwards from the - current position. Single bytes ("literals") are preceded by a one (a - single bit) and are either uncoded (the eight bits go directly into the - compressed stream for a total of nine bits) or Huffman coded with a - supplied literal code tree. If literals are coded, then the minimum match - length is three, otherwise it is two. - - There are therefore four kinds of imploded streams: 8K search with coded - literals (min match = 3), 4K search with coded literals (min match = 3), - 8K with uncoded literals (min match = 2), and 4K with uncoded literals - (min match = 2). The kind of stream is identified in two bits of a - general purpose bit flag that is outside of the compressed stream. - - Distance-length pairs for matched strings are preceded by a zero bit (to - distinguish them from literals) and are always coded. The distance comes - first and is either the low six (4K) or low seven (8K) bits of the - distance (uncoded), followed by the high six bits of the distance coded. - Then the length is six bits coded (0..63 + min match length), and if the - maximum such length is coded, then it's followed by another eight bits - (uncoded) to be added to the coded length. This gives a match length - range of 2..320 or 3..321 bytes. - - The literal, length, and distance codes are all represented in a slightly - compressed form themselves. What is sent are the lengths of the codes for - each value, which is sufficient to construct the codes. Each byte of the - code representation is the code length (the low four bits representing - 1..16), and the number of values sequentially with that length (the high - four bits also representing 1..16).

The compression - method searches for as much of the current string of bytes (up to a - length of 258) in the previous 32K bytes. If it doesn't find any - matches (of at least length 3), it codes the next byte. Otherwise, it - codes the length of the matched string and its distance backwards from - the current position. There is a single Huffman code that codes both - single bytes (called "literals") and match lengths. A second Huffman - code codes the distance information, which follows a length code. Each - length or distance code actually represents a base value and a number - of "extra" (sometimes zero) bits to get to add to the base value. At - the end of each deflated block is a special end-of-block (EOB) literal/ - length code. The decoding process is basically: get a literal/length - code; if EOB then done; if a literal, emit the decoded byte; if a - length then get the distance and emit the referred-to bytes from the - sliding window of previously emitted data. - - There are (currently) three kinds of inflate blocks: stored, fixed, and - dynamic. The compressor outputs a chunk of data at a time and decides - which method to use on a chunk-by-chunk basis. A chunk might typically - be 32K to 64K, uncompressed. If the chunk is uncompressible, then the - "stored" method is used. In this case, the bytes are simply stored as - is, eight bits per byte, with none of the above coding. The bytes are - preceded by a count, since there is no longer an EOB code. - - If the data are compressible, then either the fixed or dynamic methods - are used. In the dynamic method, the compressed data are preceded by - an encoding of the literal/length and distance Huffman codes that are - to be used to decode this block. The representation is itself Huffman - coded, and so is preceded by a description of that code. These code - descriptions take up a little space, and so for small blocks, there is - a predefined set of codes, called the fixed codes. The fixed method is - used if the block ends up smaller that way (usually for quite small - chunks); otherwise the dynamic method is used. In the latter case, the - codes are customized to the probabilities in the current block and so - can code it much better than the pre-determined fixed codes can. - - The Huffman codes themselves are decoded using a multi-level table - lookup, in order to maximize the speed of decoding plus the speed of - building the decoding tables. See the comments below that precede the - lbits and dbits tuning parameters. - - GRR: return values(?) - 0 OK - 1 incomplete table - 2 bad input - 3 not enough memory - the following return codes are passed through from FLUSH() errors - 50 (PK_DISK) "overflow of output space" - 80 (IZ_CTRLC) "canceled by user's request" - */ - - -/* - Notes beyond the 1.93a appnote.txt: - - 1. Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - 14. The Deflate64 (PKZIP method 9) variant of the compression algorithm - differs from "classic" deflate in the following 3 aspect: - a) The size of the sliding history window is expanded to 64 kByte. - b) The previously unused distance codes #30 and #31 code distances - from 32769 to 49152 and 49153 to 65536. Both codes take 14 bits - of extra data to determine the exact position in their 16 kByte - range. - c) The last lit/length code #285 gets a different meaning. Instead - of coding a fixed maximum match length of 258, it is used as a - "generic" match length code, capable of coding any length from - 3 (min match length + 0) to 65538 (min match length + 65535). - This means that the length code #285 takes 16 bits (!) of uncoded - extra data, added to a fixed min length of 3. - Changes a) and b) would have been transparent for valid deflated - data, but change c) requires to switch decoder configurations between - Deflate and Deflate64 modes. - */ - -#include <stdlib.h> -#include <stdio.h> -#include <string.h> -#include "cpio.h" -#include "unzip.h" - -/* - inflate.h must supply the uch slide[WSIZE] array, the zvoid typedef - (void if (void *) is accepted, else char) and the NEXTBYTE, - FLUSH() and memzero macros.

' -and -.RB ` [ '. -Care must be taken to quote meta-characters appropriately from the shell. -If a pattern matches the prefix name of a directory in the archive, -all files below that directory are also extracted. -File permissions are set to those in the archive; -if the caller is the super-user, -ownerships are restored as well. -options are specified. -Archives compressed with -.IR bzip2 (1), -.IR compress (1), -.IR gzip (1), -or -.IR rpm (1) -are transparently de\%compressed on input. -.PP -With -.BR \-w , -.I pax -works in -.RI ` write ' -mode, -creates archives -and writes them to standard output per default. -A list of filenames to be included in the archive is -read from standard input; -if the name of a directory appears, -all its members and the directory itself are recursively -included in the archive. -The -.IR find (1) -utility is useful to generate a list of files -(see also its -.I \-cpio -and -.I \-ncpio -operators). -When producing a filename list for -.IR pax , -find should always be invoked with -.I \-depth -since this makes it possible to extract write-protected directories -for users other than the super-user. -If -.I files -are given on the command line, -they are included in the archive -in the same manner as described above -and standard input is not read. -.PP -The -.B \-rw -options selects -.RI ` copy ' -mode; -a list of -.I files -is read from standard input -or taken from the command line -as described for -.IR \-w ; -files are copied to the specified -.IR directory , -preserving attributes as described for -.IR \-r . -Special files are re-created in the target hierarchy, -and hard links between copied files are preserved. -.PP -When a premature end-of-file is detected with -.I \-r -and -.I \-w -and the archive is a block or character special file, -the user is prompted for new media. -.PP -The following options alter the behavior of -.IR pax : -.TP -.B \-a -Append files to the archive. -The archive must be seekable, -such as a regular file or a block device, -or a tape device capable of writing between filemarks. -.TP -\fB\-b\fI size\fR[\fBw\fR|\fBb\fR|\fBk\fR|\fBm\fR] -Blocks input and output archives at -.I size -byte records. -The optional suffix multiplies -.I size -by 2 for -.BR w , -512 for -.BR b , -1024 for -.BR k , -and 1048576 for -.BR m . -.TP -.B \-c -Reverses the sense of patterns -such that a file that does not match any of the patterns -is selected. -.TP -.B \-d -Causes -.I pax -to ignore files below directories. -In read mode, -patterns matching directories -cause only the directory itself to extracted, -files below will be ignored -unless another pattern applies to them. -In write mode, -arguments or standard input lines referring to directories -do not cause files below the respective directory -to be archived. -.TP -\fB\-f\fI\ file\fR -Selects a -.I file -that is read with the -.I \-r -option instead of standard input -or written with the -.I \-w -option instead of standard output. -.TP -.B \-H -Follow symbolic links given on the command line when reading files with -.I \-w -or -.IR \-rw , -but do not follow symbolic links encountered during directory traversal. -.TP -.B \-i -Rename files interactively. -Before a file is extracted from the archive, -its file name is printed on standard error -and the user is prompted to specify a substitute file name. -If the line read from the terminal is empty, -the file is skipped; -if the line consists of a single dot, -the name is retained; -otherwise, -the line forms the new file name. -.TP -.B \-k -Causes existing files not to be overwritten. -.TP -.B \-K -Try to continue operation on read errors and invalid headers. -If an archive contains another archive, -files from either archive may be chosen. -.TP -.B \-l -Link files instead of copying them with -.I \-rw -if possible. -.TP -.B \-L -Follow symbolic links when reading files with -.I \-w -or -.IR \-rw . -.B /usr/posix2001/bin/pax -terminates immediately

60000 \ 32 -.TE -.sp -.PP -The byte order of -.B binary -cpio archives -depends on the machine -on which the archive is created. -Unlike some other implementations, -.I pax -fully supports -archives of either byte order. -.I \-x\ bbs -can be used to create an archive -with the byte order opposed to that of the current machine. -.PP -The -.B sgi -format extends the binary format -to handle larger files and more device bits. -If an archive does not contain any entries -that actually need the extensions, -it is identical to a binary archive. -.I \-x\ sgi -archives are always created in MSB order. -.PP -The -.B odc -format was introduced with System\ III -and standardized with IEEE Std. 1003.1. -All known -.I cpio -and -.I pax -implementations since around 1980 can read this format. -.PP -The -.B dec -format extends the -.I odc -format -to support more device bits. -Archives in this format are generally incompatible with -.I odc -archives -and need special implementation support to be read. -.PP -The -.B \-x\ newc -format was introduced with System\ V Release\ 4. -Except for the file size, -it imposes no practical limitations -on files archived. -The original SVR4 implementation -stores the contents of hard linked files -only once and with the last archived link. -This -.I pax -ensures compatibility with SVR4. -With archives created by implementations that employ other methods -for storing hard linked files, -each file is extracted as a single link, -and some of these files may be empty. -Implementations that expect methods other than the original SVR4 one -may extract no data for hard linked files at all. -.PP -The -.B crc -format is essentially the same as the -.I \-x\ newc -format -but adds a simple checksum (not a CRC, despite its name) -for the data of regular files. -The checksum requires the implementation to read each file twice, -which can considerably increase running time and system overhead. -As not all implementations claiming to support this format -handle the checksum correctly, -it is of limited use. -.PP -The -.B sco -and -.B scocrc -formats are variants of the -.I \-x\ newc -and -.I \-x\ crc -formats, respectively, -with extensions to support larger files. -The extensions result in a different archive format -only if files larger than slightly below 2\ GB occur. -.PP -The -.B cray -format extends all header fields to 64 bits. -It thus imposes no practical limitations of any kind -on archived files, -but requires special implementation support -to be read. -Although it is originally a binary format, -the byte order is always MSB as on Cray machines. -The -.B cray5 -format is an older variant -that was used with UNICOS 5 and earlier. -.PP -The -.B otar -format was introduced with the Unix 7th Edition -.I tar -utility. -Archives in this format -can be read on all Unix systems since about 1980. -It can only hold regular files -(and, on more recent systems, symbolic links). -For file names that contain characters with the most significant bit set -(non-ASCII characters), -implementations differ in the interpretation of the header checksum. -.PP -The -.B ustar -format was introduced with IEEE Std. 1003.1. -It extends the old -.I tar -format -with support for directories, device files, -and longer file names. -Pathnames of single-linked files can consist of up to 256 characters, -dependent on the position of slashes. -Files with multiple links can only be archived -if the first link encountered is no longer than 100 characters. -Due to implementation errors, -file names longer than 99 characters -can not considered to be generally portable. -Another addition of the -.I ustar -format -are fields for the symbolic user and group IDs. -These fields are created by -.IR pax , -but ignored when reading such archives. -.PP -With -.BR "\-x tar" , -a variant of the -.I ustar -format is selected -which stores file type bits in the mode field -to work around common implementation problems. -These bits are ignored by -.I pax -when reading archives. -.PP -The -.B pax -format is an extension to the -.I ustar -format. -If attributes cannot be archived with -.IR ustar , -an extended header is written. -Unless the size of an entry is greater than 8\ GB, -a -.I pax -archive should be readable by any implementation -capable of reading -.I ustar -archives, -although files may be extracted under wrong names -and extended headers may be extracted as separate files. -If a file name contains non-UTF-8 characters, -it may not be archived or extracted correctly -because of a problem of the -.I pax -format specification. -.PP -The -.B sun -format extends the -.I ustar -format similar as the -.I pax -format does. -The extended headers in -.I sun -format archives are not understood -by implementations that support only the -.I pax -format and vice-versa. -The -.I sun -format has also problems with non-UTF-8 characters in file names. -.PP -The -.B GNU -.I tar -format is mostly compatible with the other -.I tar -formats, -unless an archive entry actually uses its extended features. -There are no practical limitations on files archived with this format. -The implementation of -.I pax -is limited to expanded numerical fields -and long file names; -in particular, -there is no support for sparse files or incremental backups. -If -.I pax -creates a multi-volume -.I GNU -archive, -it just splits a single-volume archive in multiple parts, -as with the other formats; -.I GNU -multi-volume archives are not supported. -.PP -The -.B bar -format is similar to the -.I tar -format, but can store longer file names. -It requires special implementation support to be read. -.PP -The -.B zip -format can be read in many non-Unix environments. -There are several restrictions on archives -intended for data exchange: -only regular files should be stored; -file times, permissions and ownerships -might be ignored by other implementations; -there should be no more than 65536 files in the archive; -the total archive size should not exceed 2 GB; -only -.I deflate -compression should be used. -Otherwise, -.I pax -stores all information available with other archive formats -in extended -.I zip -file headers, -so if archive portability is of no concern, -the -.I zip -implementation in -.I pax -can archive complete Unix file hierarchies. -.I Pax -supports the -.I zip64 -format extension for large files; -it automatically writes -.I zip64 -entries if necessary. -.I Pax -can extract all known -.I zip -format compression codes. -It does not support -.I zip -encryption. -Multi-volume -.I zip -archives are created as splitted single-volume archives, -as with the other formats written by -.IR pax ; -generic multi-volume -.I zip -archives are not supported. -.SH EXAMPLES -Extract all files named -.I Makefile -or -.I makefile -from the archive stored on -.IR /dev/rmt/c0s0 , -overwriting recent files: -.RS 2 -.sp -pax \-r \-f /dev/rmt/c0s0

[Note that partial clearing can "orphan" - nodes: the parent-to-be can be cleared before its new child is added, - but the child is added anyway (as an orphan, as though the parent still - existed). When the tree fills up to the point where the parent node is - reused, the orphan is effectively "adopted." Versions prior to 1.05 were - affected more due to greater use of pointers (to children and siblings - as well as parents).] - - This replacement version of unshrink.c was written from scratch. It is - based only on the algorithms described in Mark Nelson's _The Data Compres- - sion Book_ and in Terry Welch's original paper in the June 1984 issue of - IEEE _Computer_; no existing source code, including any in Nelson's book, - was used. - - Memory requirements have been reduced in this version and are now no more - than the original Sam Smith code. This is still larger than any of the - other algorithms: at a minimum, 8K+8K+16K (stack+values+parents) assuming - 16-bit short ints, and this does not even include the output buffer (the - other algorithms leave the uncompressed data in the work area, typically - called slide[]). For machines with a 64KB data space this is a problem, - particularly when text conversion is required and line endings have more - than one character. UnZip's solution is to use two roughly equal halves - of outbuf for the ASCII conversion in such a case; the "unshrink" argument - to flush() signals that this is the case. - - For large-memory machines, a second outbuf is allocated for translations, - but only if unshrinking and only if translations are required. - - | binary mode | text mode - --------------------------------------------------- - big mem | big outbuf | big outbuf + big outbuf2 <- malloc'd here - small mem | small outbuf | half + half small outbuf - - Copyright 1994, 1995 Greg Roelofs.

Can I use the source code of Zip and UnZip in my commercial - application? - - A. Yes, so long as you include in your product an acknowledgment; a - pointer to the original, free compression sources; and a statement - making it clear that there are no extra or hidden charges resulting - from the use of our compression code in your product (see below for - an example). The acknowledgment should appear in at least one piece - of human-readable documentation (e.g., a README file or man page), - although additionally putting it in the executable(s) is OK, too. - In other words, you are allowed to sell only your own work, not ours, - and we'd like a little credit. (Note the additional restrictions - above on the code in unreduce.c, unshrink.c, vms.c, time_lib.c, and - everything in the wince and windll subdirectories.) Contact us at - Zip-Bugs@lists.wku.edu if you have special requirements. We also - like to hear when our code is being used, but we don't require that. - - <Product> incorporates compression code from the Info-ZIP group. - There are no extra charges or costs due to the use of this code, - and the original compression sources are freely available from - http://www.cdrom.com/pub/infozip/ or ftp://ftp.cdrom.com/pub/infozip/ - on the Internet. - - If you only need compression capability, not full zipfile support, - you might want to look at zlib instead; it has fewer restrictions - on commercial use.
