* various header cleanups, some related to _BSD_SOURCE additionRich Felker2012-05-221-2/+1
| | | | | | there is no reason to avoid multiple identical macro definitions; this is perfectly legal C, and even with the maximal warning options enabled, gcc does not issue any warning for it.
* support _BSD_SOURCE feature test macroRich Felker2012-05-221-1/+13
| | | | | patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
* add support for ugly *64 functions with _LARGEFILE64_SOURCERich Felker2012-05-041-0/+10
| | | | | | | | | | | | | | | | musl does not support legacy 32-bit-off_t whatsoever. off_t is always 64 bit, and correct programs that use off_t and the standard functions will just work out of the box. (on glibc, they would require -D_FILE_OFFSET_BITS=64 to work.) however, some programs instead define _LARGEFILE64_SOURCE and use alternate versions of all the standard types and functions with "64" appended to their names. we do not want code to actually get linked against these functions (it's ugly and inconsistent), so macros are used instead of prototypes with weak aliases in the library itself. eventually the weak aliases may be added at the library level for the sake of using code that was originally built against glibc, but the macros will still be the desired solution in the headers.
* move F_DUPFD_CLOEXEC out of bitsRich Felker2012-04-151-0/+2
| | | | | | fcntl values 1024 and up are universal, arch-independent. later I'll add some of the other linux-specific ones for notify, leases, pipe size, etc. here too.
* fix O_SYNC definition, cleanup fcntl.hRich Felker2011-04-141-0/+8
|
* fcntl.h: move macros that do not vary between archs out of bitsRich Felker2011-04-141-0/+24
|
* fcntl.h should make availabel the mode constants from sys/stat.hRich Felker2011-03-081-0/+18
| | | | also remove some legacy nonsense that crept in.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+43
