wcscasecmp(3)
NAME
wcscasecmp - compare two wide-character strings, ignoring case
SYNOPSIS
#define _GNU_SOURCE #include <wchar.h> int wcscasecmp(const wchar_t *s1, const wchar_t *s2);
DESCRIPTION
The wcscasecmp() function is the wide-character equivalent of the strcasecmp(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 positive integer if s1 is greater than s2, ignoring case. It returns a
negative integer if s1 is smaller than s2, ignoring case.
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.
