2011-10-17add some missing GNU FNM_* extensions to the headerRich Felker-1/+3
note that none of these are implemented, and programs depending on them may break... patch by sh4rm4
2011-10-17fix some details in ugly stuff that doesn't belong in libcRich Felker-0/+2
patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
2011-10-04make [U]INTn_C() macros have the right type...Rich Felker-4/+4
...and still be valid in #if directives.
2011-09-28stupid typo (caused by rather ugly spelling in POSIX..) in aioRich Felker-1/+1
2011-09-26fix ctype macros to cast argument to (unsigned) firstRich Felker-7/+7
issue reported by nsz, but it's actually not just pedantic. the functions can take input of any arithmetic type, including floating point, and the behavior needs to be as if the conversion implicit in the function call took place.
2011-09-26cleanup various minor issues reported by nszRich Felker-2/+1
the changes to syscall_ret are mostly no-ops in the generated code, just cleanup of type issues and removal of some implementation-defined behavior. the one exception is the change in the comparison value, which is fixed so that 0xf...f000 (which in principle could be a valid return value for mmap, although probably never in reality) is not treated as an error return.
2011-09-23FD_ISSET must return an int. this is the easiest way.Rich Felker-1/+1
casting to int would not be correct because high bits could be lost. mapping the high bits down onto low bits would be costlier in the common case where the result is just used in a conditional. changing the type of the bit array elements to int would permute the order of the bit array on 64-bit big endian systems, so that's not an option either.

2011-09-20fix incorrect include guard in mqueue.hRich Felker-2/+2
2011-09-20fix the fsid_t structure to match name of __valRich Felker-1/+1
this is a case of poorly written man pages not matching the actual implementation, and why i hate implementing nonstandard interfaces with no actual documentation of how they're intended to work.
2011-09-20fix broken siginfo_t with _GNU_SOURCE definedRich Felker-6/+5
this bug was introduced in a recent patch. the problem we're working around is that broken GNU software wants to use "struct siginfo" rather than "siginfo_t", but "siginfo" is not in the reserved namespace and thus not legal for the standard header to use.
2011-09-19fix the definition of struct statvfs to match lsb abiRich Felker-7/+24
at the same time, make struct statfs match the traditional definition and make it more useful, especially the fsid_t stuff.
2011-09-19add some more siginfo aliases broken software expects...Rich Felker-0/+2
2011-09-19cleanup redundancy in bits/signal.h versionsRich Felker-4/+108
2011-09-19fix the type of wchar_t on arm; support wchar_t varying with archRich Felker-15/+6
really wchar_t should never vary, but the ARM EABI defines it as an unsigned 32-bit int instead of a signed one, and gcc follows this nonsense. thus, to give a conformant environment, we have to follow (otherwise L""[0] and L'\0' would be 0U rather than 0, but the application would be unaware due to a mismatched definition for WCHAR_MIN and WCHAR_MAX, and Bad Things could happen with respect to signed/unsigned comparisons, promotions, etc.). fortunately no rules are imposed by the C standard on the relationship between wchar_t and wint_t, and WEOF has type wint_t, so we can still make wint_t always-signed and use -1 for WEOF.
2011-09-19fix broken multi-inclusion guard in sys/reg.hRich Felker-2/+2
2011-09-18cleanup more bits cruft (sysmacros and socket)Rich Felker-1/+199

2011-09-18overhaul clone syscall wrappingRich Felker-0/+27
several things are changed. first, i have removed the old __uniclone function signature and replaced it with the "standard" linux __clone/clone signature. this was necessary to expose clone to applications anyway, and it makes it easier to port __clone to new archs, since it's now testable independently of pthread_create. secondly, i have removed all references to the ugly ldt descriptor structure (i386 only) from the c code and pthread structure. in places where it is needed, it is now created on the stack just when it's needed, in assembly code. thus, the i386 __clone function takes the desired thread pointer as its argument, rather than an ldt descriptor pointer, just like on all other sane archs. this should not affect applications since there is really no way an application can use clone with threads/tls in a way that doesn't horribly conflict with and clobber the underlying implementation's use. applications are expected to use clone only for creating actual processes, possibly with new namespace features and whatnot.
2011-09-15implement ptrace syscall wrapper (untested)Rich Felker-1/+1
2011-09-13fix return types for aio_read and aio_write againRich Felker-2/+2
previous fix was backwards and propagated the wrong type rather than the right one...
2011-09-13fix various errors in function signatures/prototypes found by nszRich Felker-8/+8
2011-09-13fix prototypes for aio_read and aio_writeRich Felker-2/+2
2011-09-12implement gnu sigisemptysetRich Felker-0/+1
2011-09-11add prototypes for GNU *_unlocked stdio functionsRich Felker-0/+4
actually these are just weak aliases for the normal locking versions right now, and they will probably stay that way since making them lock-free without slowing down the normal versions would require significant code duplication for no benefit.
2011-09-11add dummied strverscmp (obnoxious GNU function)Rich Felker-0/+1
programs that use this tend to horribly botch international text support, so it's questionable whether we want to support it even in the long term... for now, it's just a dummy that calls strcmp.
2011-09-11declare alloca in stdlib.h when _GNU_SOURCE is definedRich Felker-0/+1
2011-09-09implement POSIX asynchronous ioRich Felker-0/+60
some features are not yet supported, and only minimal testing has been performed. should be considered experimental at this point.
2011-09-03implement fmemopenRich Felker-0/+1
testing so far has been minimal. may need further work.
2011-09-03implement open_wmemstreamRich Felker-0/+1
not heavily tested, but it seems to be correct, including the odd behavior that seeking is in terms of wide character count. this precludes any simple buffering, so we just make the stream unbuffered.
2011-09-03implement open_memstreamRich Felker-0/+1
this is the first attempt, and may have bugs. only minimal testing has been performed.
2011-09-02fix missing prototypes/wrong signature for psiginfo, psignalRich Felker-0/+3
2011-08-27fix broken FD_* macros on 64-bit targetsRich Felker-3/+3
1 is too small if int is 32-bit but unsigned long is 64-bit. be explicit and use 1UL.
2011-08-14macro for pthread_equalRich Felker-0/+2
no sense bloating apps with a function call for an equality comparison...
2011-08-12implement forkallRich Felker-0/+1
this is a "nonstandard" function that was "rejected" by POSIX, but nonetheless had its behavior documented in the POSIX rationale for fork. it's present on solaris and possibly some other systems, and duplicates the whole calling process, not just a single thread. glibc does not have this function. it should not be used in programs intending to be portable, but may be useful for testing, checkpointing, etc. and it's an interesting (and quite small) example of the usefulness of the __synccall framework originally written to work around deficiencies in linux's setuid syscall.
2011-07-31consistency: use struct __ucontext instead of ucontext_t in prototypesRich Felker-1/+1
this is necessary to avoid build errors if feature test macros are not properly defined when including ucontext.h
2011-07-09add missing signalfd flagsRich Felker-0/+3
2011-06-30fill in junk in stropts.hRich Felker-1/+123
STREAMS are utterly useless as far as I can tell, but some software was apparently broken by the presence of stropts.h but lack of macros it's supposed to define...
2011-06-30add and consolidate nasty stdio_ext junkRich Felker-0/+27
hopefully this resolves the rest of the issues with hideously nonportable hacks in programs that use gnulib.
2011-06-30implement the nonstandard GNU function fpurgeRich Felker-0/+1
this is a really ugly and backwards function, but its presence will prevent lots of broken gnulib software from trying to define its own version of fpurge and thereby failing to build or worse.
2011-06-29avoid errors in ucontext.h when no feature test macros are definedRich Felker-3/+5
