WCSCASECMP(3) Linux Programmer's Manual WCSCASECMP(3) NAME wcscasecmp - compare two wide-character strings, ignoring case SYNOPSIS #include <wchar.h> int wcscasecmp(const wchar_t *s1, const wchar_t *s2); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): wcscasecmp(): Since glibc 2.10: _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L Before glibc 2.10: _GNU_SOURCE DESCRIPTION The wcscasecmp() function is the wide-character equivalent of the str- casecmp(3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, ignoring case differences (towupper(3), towlower(3)). RETURN VALUE The wcscasecmp() function returns zero if the wide-character strings at s1 and s2 are equal except for case distinctions. It returns a posi- tive integer if s1 is greater than s2, ignoring case. It returns a negative integer if s1 is smaller than s2, ignoring case. VERSIONS The wcscasecmp() function is provided in glibc since version 2.1. ATTRIBUTES Multithreading (see pthreads(7)) The wcscasecmp() function is thread-safe with exceptions. It can be safely used in multithreaded applications, as long as setlocale(3) is not called to change the locale during its execution. CONFORMING TO POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems. NOTES The behavior of wcscasecmp() depends on the LC_CTYPE category of the current locale.
