WCSCASECMP(3) Linux Programmer's Manual WCSCASECMP(3)NAMEwcscasecmp - compare two wide-character strings, ignoring case
int wcscasecmp(const wchar_t *s1, const wchar_t *s2);
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)).
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.
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is
not widely available on other systems.
The behavior of wcscasecmp() depends on the LC_CTYPE category of the
