2011-06-06use __attribute__((const)) for errno and pthread_self if __GNUC__ is definedRich Felker2-0/+6
this is not too ugly and should result in significant code size and performance improvements for many programs.
2011-06-06fix handling of d_name in struct direntRich Felker1-1/+1
basically there are 3 choices for how to implement this variable-size string member: 1. C99 flexible array member: breaks using dirent.h with pre-C99 compiler. 2. old way: length-1 string: generates array bounds warnings in caller. 3. new way: length-NAME_MAX string. no problems, simplifies all code. of course the usable part in the pointer returned by readdir might be shorter than NAME_MAX+1 bytes, but that is allowed by the standard and doesn't hurt anything.
2011-05-30missing prototypes for mbsnrtowcs and wcsnrtombsRich Felker1-0/+6
2011-05-30implement pthread_[sg]etconcurrency.Rich Felker1-0/+3
there is a resource limit of 0 bits to store the concurrency level requested. thus any positive level exceeds a resource limit, resulting in EAGAIN. :-)
2011-05-28initial implementation of posix_spawnRich Felker1-0/+67
file actions are not yet implemented, but everything else should be mostly complete and roughly correct.
2011-05-08eventfd syscall wrapper and read/write wrappersRich Felker1-0/+25
2011-05-05add SA_NOMASK alias for SA_NODEFER with _GNU_SOURCERich Felker1-0/+1
2011-04-27use compiler builtins for variadic macros when availableRich Felker1-0/+7
this slightly cuts down on the degree musl "fights with" gcc, but more importantly, it fixes a critical bug when gcc inlines a variadic function and optimizes out the variadic arguments due to noticing that they were "not used" (by __builtin_va_arg). we leave the old code in place if __GNUC__ >= 3 is false; it seems like it might be necessary at least for tinycc support and perhaps if anyone ever gets around to fixing gcc 2.95.3 enough to make it work..
2011-04-27correct variadic prototypes for execl* familyRich Felker1-3/+3
the old versions worked, but conflicted with programs which declared their own prototypes and generated warnings with some versions of gcc.
2011-04-26function signature fix: add const qualifier to mempcpy src argRich Felker1-1/+1
2011-04-26typo in prototype for mempcpyRich Felker1-1/+1
2011-04-26prototype for mempcpyRich Felker1-0/+1
2011-04-21move wait.h macros out of bits. they do not vary.Rich Felker2-3/+30
2011-04-21include signal.h to avoid thorny __sigcontext/sigcontext issuesRich Felker1-2/+2
this is explicitly allowed by POSIX
2011-04-20implement (nonstandard) forkptyRich Felker1-0/+1
2011-04-14fix O_SYNC definition, cleanup fcntl.hRich Felker1-0/+8
2011-04-14fcntl.h: move macros that do not vary between archs out of bitsRich Felker1-0/+24
2011-04-14add useless type fd_mask. it's in the reserved namespace.Rich Felker1-0/+2
2011-04-13numerous fixes to sysv ipcRich Felker3-13/+55
some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface. as much as possible has now been moved out of bits/* these changes break abi (the old abi for these functions was wrong), but since they were not working anyway it can hardly matter.
2011-04-13add syslog.h cruft for syslogd to use...Rich Felker1-0/+45
2011-04-13add profile for getmntent_rRich Felker1-0/+1
2011-04-13fix typos on RLIM_NLIMITS, remove _GNU_SOURCE test for itRich Felker1-3/+1
RLIM_* is in the reserved namespace for this header
2011-04-13fix and cleanup suseconds_t/timeval stuff (broken on 64-bit)Rich Felker2-9/+1
trash in the upper 32 bits was making the kernel sleep forever in select on 64-bit systems.
2011-04-13fix prototypes/signature for setgroups, etc.Rich Felker2-1/+7
2011-04-13fix incorrect GNU sighandler_t typedefRich Felker1-1/+1
2011-04-13implement memrchr (nonstandard) and optimize strrchr in terms of itRich Felker1-0/+1
2011-04-13add ptsname_r (nonstandard) and split ptsname (standard) to separate fileRich Felker1-0/+1
this eliminates the ugly static buffer in programs that use ptsname_r.
2011-04-12move bswap functions to static inline in byteswap.hRich Felker1-0/+25
2011-04-12utmpx.h is no longer under standards, so expose ut_exit structureRich Felker1-3/+3
2011-04-12add some traditional aliases to stat.hRich Felker1-0/+6
2011-04-12add missing rlimit macrosRich Felker1-0/+8
2011-04-11more types cleanupRich Felker1-12/+3
the basic idea is that the only things in alltypes.h should be types that either vary from system to system (in practice, not just in theoretical la-la land - this is the implementation so we choose what constraints we want to impose on ports) or which are needed by multiple system headers.
2011-04-11cleanup types stuff in headers, fix missing u_int*_t in sys/types.hRich Felker2-7/+19
2011-04-10add some ugly legacy type names in sys/types.h (u_char etc.)Rich Felker1-0/+8
2011-04-10add legacy BSD-style timer*() macros in sys/time.hRich Felker1-0/+10
2011-04-10add missing UTIME_* macros in sys/stat.hRich Felker1-0/+3
2011-04-06fix typo in sys/msg.hRich Felker1-1/+1
2011-04-06add IN_LOOPBACKNET constant (nonstandard but in reserved namespace)Rich Felker1-0/+2
2011-04-06fix prototype for strsepRich Felker1-1/+1
2011-04-06fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functionsRich Felker1-1/+1
2011-04-05getopt.h is a GNU-getopt-specific header. always expose GNU functions.Rich Felker1-2/+0
2011-04-05add sysexits.h legacy headerRich Felker1-0/+21
2011-04-05add more legacy functions: setlinebuf and setbufferRich Felker1-0/+2
2011-04-05alternate name for syslog.hRich Felker1-0/+1
2011-04-05support the nonstandard err.h interfacesRich Felker1-0/+24
note that unlike the originals, these do not print the program name/argv[0] because we have not saved it anywhere. this could be changed in __libc_start_main if desired.
2011-04-03prototype getdtablesize (nonstandard function)Rich Felker1-0/+1
2011-04-03add setresuid/setresgid functions (nonstandard)Rich Felker1-0/+2
2011-04-03d_fileno alias for d_ino in direntRich Felker1-0/+2
this is nonstandard but since POSIX reserved d_ prefix in dirent.h we might as well define it unconditionally. some programs depend on it.
2011-04-01remove obsolete and useless useconds_t typeRich Felker1-3/+2
2011-04-01fix misspelled PTHREAD_CANCELED constantRich Felker1-1/+1
