* Feature test macros overhaul: string.h and strings.h overlapsYaakov Selkowitz2016-04-131-7/+7
| | | | | | | | | | | strings.h is the header mandated for these functions in POSIX.1 prior to 2008 (when most of these were removed). The declarations in string.h are only for BSD compatibility. But when both headers are included, avoid duplicate declarations. Also, mark stpcpy and stpncpy as POSIX.1-2008. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Feature test macros overhaul: string.hYaakov Selkowitz2016-03-171-23/+15
| | | | | | | | | | | | | | Throughout, remove __STRICT_ANSI__ and use the proper internal macros. bcmp, bcopy, bzero, index, and rindex were in POSIX prior to 2008. memrchr is GNU. strdup and strndup are POSIX.1-2008. The int-returning form of strerror_r is POSIX.1-2001. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Rework handling of basename variantsYaakov Selkowitz2015-07-061-2/+2
| | | | | | | | | | | | | | | | As a commonly-included header, the #define basename in <string.h> can affect code which uses "basename" for its own purposes (e.g. struct members or C++ namespaced functions). When such cases occur and some code includes <string.h> and some not, then errors result. OTOH, <libgen.h> is rarely used, and that's where the renaming occurs in glibc, so code using <libgen.h> should already be safe. * libc/include/libgen.h (basename): Define as __xpg_basename for source compatibility with glibc. Declare with __ASMNAME("basename") for ABI compatibility. * libc/include/string.h (basename): Define as basename for source compatibility with glibc. Declare with __ASMNAME("__gnu_basename") for ABI compatibility.
* Fix basename prototype collision string.h vs libgen.hCorinna Vinschen2015-04-231-11/+13
| | | | | | | | | | * libc/include/libgen.h (basename): Drop defining _BASENAME_DEFINED. Always define macro basename. Add comment to explain why. * libc/include/string.h (basename): Check for basename instead of _BASENAME_DEFINED. Drop __GNUC__ branch, always use basename macro. Change comment to explain why. Add nonnull function attribute. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
