2017-11-29ssp: add Object Size Checking for string.hYaakov Selkowitz1-0/+4
The implementation is from NetBSD, with the addition of mempcpy (a GNU extension) for parity with glibc and libssp. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2017-11-28Make __nonnull macro compatible with glibcYaakov Selkowitz1-1/+1
This form allows for multiple arguments, e.g. __nonnull((1,2)). Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2017-08-25Port strnstr.c to newlib.Sichen Zhao1-0/+3
2017-07-07Rename __in and __out in headers to avoid collision with Windows APIsDavid Macek1-9/+9
* string.h: Local variables in expansion of strdupa and strndupa * sys/wait.h: Fields in anonymous union in expansion of __wait_status_to_int
2017-07-05Synchronize <strings.h> with latest FreeBSDSebastian Huber1-28/+4
Include <strings.h> in <string.h> if __BSD_VISIBLE like on FreeBSD. Remove redundant declarations from <string.h>. Make ffsl(), ffsll(), strncasecmp(), strcasecmp_l(), and strncasecmp_l() visible via __BSD_VISIBLE instead of __GNU_VISIBLE. Add fls(), flsl(), and flsll() to <strings.h> if __BSD_VISIBLE. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
2017-06-19string: add strverscmpYaakov Selkowitz1-0/+4
The actual implementation is from musl (MIT license). Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2017-03-22Rename <sys/_locale.h> to <xlocale.h>Yaakov Selkowitz1-1/+1
The locale_t type is provided by <xlocale.h> on Linux, FreeBSD, and Darwin. While, like on some of those systems, it is automatically included by <locale.h> with the proper feature test macros, its presence under this particular name is still presumed in real-world software. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2016-08-25Add strerror_l prototype, change str[n]casecmp_l feature testsBrian Inglis1-6/+7
strerror_l prototype was missing. str[n]casecmp_l feature tests in string.h vs. strings.h were transposed.
2016-08-15Add sys/_locale.h header and fix up headersCorinna Vinschen1-3/+2
Signed-off by: Corinna Vinschen <corinna@vinschen.de>
2016-08-15Implement per-locale string functionsCorinna Vinschen1-0/+13
strcasecmp_l, strcoll_l, strncasecmp_l, strxfrm_l, wcscasecmp_l, wcscoll_l, wcstrncasecmp_l, wcstrxfrm_l, strftime_l. Add missing CHEWOUT_FILES from previous patch. TODO: strfmon_l. Signed-off by: Corinna Vinschen <corinna@vinschen.de>
2016-04-13Feature test macros overhaul: string.h and strings.h overlapsYaakov Selkowitz1-7/+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>
2016-03-18Add timingsafe_memcmp()Sebastian Huber1-0/+1

2016-03-17Feature test macros overhaul: string.hYaakov Selkowitz1-23/+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>
2015-07-06Rework handling of basename variantsYaakov Selkowitz1-2/+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.
2015-04-23Fix basename prototype collision string.h vs libgen.hCorinna Vinschen1-11/+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>
