NAME

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

SYNOPSIS

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       POSIX.1-2008.  This function is not specified in POSIX.1-2001,  and  is
48       not widely available on other systems.

NOTES

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