NAME

6       wcscasecmp - compare two wide-character strings, ignoring case

SYNOPSIS

10
11       int wcscasecmp(const wchar_t *s1, const wchar_t *s2);

15       wcscasecmp():
16           Since glibc 2.10:
17               _POSIX_C_SOURCE >= 200809L
18           Before glibc 2.10:

DESCRIPTION

22       The  wcscasecmp() function is the wide-character equivalent of the str‐
23       casecmp(3) function.  It compares the wide-character string pointed  to
24       by  s1  and  the  wide-character string pointed to by s2, ignoring case
25       differences (towupper(3), towlower(3)).
26

RETURN VALUE

28       The wcscasecmp() function returns zero if the wide-character strings at
29       s1  and  s2 are equal except for case distinctions.  It returns a posi‐
30       tive integer if s1 is greater than s2, ignoring  case.   It  returns  a
31       negative integer if s1 is smaller than s2, ignoring case.
32

VERSIONS

34       The wcscasecmp() function is provided in glibc since version 2.1.

CONFORMING TO

47       not widely available on other systems.

NOTES

50       The  behavior  of  wcscasecmp() depends on the LC_CTYPE category of the
51       current locale.
