wcscasecmp(3) -- Linux man page
NAME
wcscasecmp - compare two wide-character strings, ignoring case
SYNOPSIS
#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 function. It compares the wide-character string pointed to
by s1 and the wide-character string pointed to by s2, ignoring
case differences (towupper, towlower).
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
This function is a GNU extension.
SEE ALSO
strcasecmp(3),
wcscmp(3)
NOTES
The behaviour of wcscasecmp depends on the LC_CTYPE category of the
current locale.
