My version differs from -the GNU version in that it does not support debugging hooks, and does -not record statistics. Therefore it is slightly faster. - -In order to safely link programs using this malloc with a C library -that provides a different malloc, you need to make sure that -malloc(), free(), and realloc() are defined in a single object file. -Otherwise when linking you might get a combination of this malloc() -with the library's free(). The Makefile builds such an object file, -alloc.o. - -If you are using this malloc as the allocator for a C library of your -own, and are not linking with another C library, then you don't need -alloc.o. If you are building a C library, you should also write a -replacement for the file "morecore.c" that doesn't pollute the name -space. - -The header file "malloc.h" in this directory is NOT intended to be a -public header file; it is for internal use by malloc and its -friends. Don't install malloc.h in a public include directory! - -When porting this allocator to a new machine or operating system, you -should inspect the definition of BLOCKSIZE in malloc.h to make sure -it is greater than or equal to your target machine's virtual memory -page size; otherwise valloc() won't work properly. (If you don't -care about valloc() then BLOCKSIZE doesn't matter.) - -You will also need to provide a machine-dependent _default_morecore() -function; see morecore.c for a sample version that works on Unix. -Your morecore function should return a pointer to a newly allocated -region of the given size, aligned on the most pessimistic alignment -boundary for the machine. Subsequent calls to morecore should return -contiguous memory, and calls to morecore with a negative argument -should return memory to the system. If no memory is available -morecore should return NULL. - -Bug reports to Mike Haertel, mike@cs.uoregon.edu. -This version is dated March 26, 1993; include this -date with your bug report. |
