default features: make musl usable without feature test macros 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. 2012-09-08 07:13:55 +04:00			`#include <features.h>`

make brace placement in public header struct definitions consistent placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch//bits -name '.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives. 2016-07-03 21:40:11 +03:00			`struct group {`

add fgetgrent function based on patch by Isaac Dunham, moved to its own file to avoid increasing bss on static linked programs not using this nonstandard function but using the standard getgrent function, and vice versa. 2013-02-17 22:21:56 +04:00			`#ifdef _GNU_SOURCE`
remove parameter names from public headers inclusion of these names was unintentional and in most cases is a namespace violation. Daniel Sabogal tracked down and reported these. 2016-10-21 00:04:37 +03:00			`struct group fgetgrent(FILE );`
add put*ent functions for passwd/group files and similar for shadow since shadow does not yet support enumeration (getspent), the corresponding FILE-based get and put versions are also subbed out for now. this is partly out of laziness and partly because it's not clear how they should work in the presence of TCB shadow files. the stubs should make it possible to compile some software that expects them to exist, but such software still may not work properly. 2013-04-05 03:23:47 +04:00			`int putgrent(const struct group , FILE );`

support _BSD_SOURCE feature test macro patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible. 2012-05-23 05:52:08 +04:00			`#if defined(_GNU_SOURCE) \|\| defined(_BSD_SOURCE)`
