2012-12-03feature test macros: make _GNU_SOURCE enable everythingRich Felker-7/+2
previously, a few BSD features were enabled only by _BSD_SOURCE, not by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other feature test macros, this made adding _GNU_SOURCE to a project not a purely additive feature test macro; it actually caused some features to be suppressed. most of the changes made by this patch actually bring musl in closer alignment with the glibc behavior for _GNU_SOURCE. the only exceptions are the added visibility of functions like strlcpy which were BSD-only due to being disliked/rejected by glibc maintainers. here, I feel the consistency of having _GNU_SOURCE mean "everything", and especially the property of it being purely additive, are more valuable than hiding functions which glibc does not have.
2012-09-07default features: make musl usable without feature test macrosRich Felker-5/+1
the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-1/+7
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.

2012-06-13add (currently stubbed due to stubbed strverscmp) versionsort functionRich Felker-0/+5
based on patch by Emil Renner Berthing, with minor changes to dirent.h for LFS64 and organization of declarations this code should work unmodified once a real strverscmp is added, but I've been hesitant to add it because the GNU strverscmp behavior is harmful in a lot of cases (for instance if you have numeric filenames in hex). at some point I plan on trying to design a variant of the algorithm that behaves better on a mix of filename styles.
2012-06-04_GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCERich Felker-1/+1
this is ugly and stupid, but now that the *64 symbol names exist, a lot of broken GNU software detects them in configure, then either breaks during build due to missing off64_t definition, or attempts to compile without function declarations/prototypes. "fixing" it here is easier than telling everyone to add yet another feature test macro to their builds.
2012-05-22support _BSD_SOURCE feature test macroRich Felker-1/+1
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
2012-05-04add support for ugly *64 functions with _LARGEFILE64_SOURCERich Felker-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.
2011-06-06fix handling of d_name in struct direntRich Felker-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.
2011-04-03d_fileno alias for d_ino in direntRich Felker-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.
