2024-07-09stdlib: increase number of static atexit handlers to 32Yann Le Du
The existing limit of 20 was found to be insufficient when moving from gcc 8 to gcc 9. At the time a test ran already 16 handlers had been installed leaving only minimal room for application installed handlers. Musl uses 32, as does newlib. Further, the ISO C standard for C99 specifies that: The implementation shall support the registration of at least 32 functions. (7.20.4.2 The atexit function) Co-authored-by: Yann Le Du <yann.le.du@kernkonzept.com> Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>

2022-05-23libc/misc/getloadavg: Add getloadavg support to uClibc-nglancethepants
This borrows getloadavg.c from musl. getloadavg pops up often. Recently llvm and rust are dependent on it. glibc and musl have it and no-one actually checks if it's available in your libc. It's just become way easier to add it in uclibc-ng rather than patch everything else. Signed-off-by: Lance Fredrickson <lancethepants@gmail.com>
2018-01-31remove arc4random (rc4 based)Waldemar Brodkorb
OpenBSD arc4random is using chacha20 cipher algorithm for a long time. This copy is still based on deprecated rc4 cipher algorithm. We could either update the arc4random.c or drop it. Drop it. Users should better use libbsd when using arc4random interface. Musl/glibc does not have arc4random either.

Add __LEAF to all __THROW, introduce non-leaf __THROWNL Adjust affected spots accordingly. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless. Really, the point of this is to stay in sync with what glibc did. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-18Replace FSF snail mail address with URLsMike Frysinger
This matches a similar change made to glibc. No functional changes here. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-06-15stdlib.h, arc4random.c: fix arc4random return type to u_int32_tPeter S. Mazinger
Change uint32_t to u_int32_t and uint8_t to u_int8_t, removing completely the dependency on stdint.h. Based on patch by Timo Teraes <timo.teras@iki.fi>. His comment: This also fixes a major bug that stdlib.h includes stdint.h. Things might go very wrong because stdint.h has conditional defines and if stdlib.h is included before #define's for stdint.h we end up missing things and breaking builds (e.g. openjdk).

2012-05-02rpmatch: fix previous commit w/C++ compilersMike Frysinger
The throw markings on the inline func trigger errors when building with C++. Since this inline version doesn't throw any exceptions, just drop the markings completely and be done with it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-30rpmatch: simple inline versionMike Frysinger
Since rpmatch will match ^[Yy] and ^[Nn] regardless of locale, this lets us create a simple inline version. Newer procps versions use this function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-20note that we do not want hidden malloc aliasesMike Frysinger
We want to let malloc() and friends be overridable at runtime so that apps can insert their own implementation (think debugging, specialized setups, etc...). That means that C library functions that return allocated memory have to go through the normal malloc() symbol as well as the external code is the one who will be calling free().

2009-03-25- Add strtouq alias (to strtoul) for 64bitBernhard Reutner-Fischer
