wcscasecmp — compare two wide-character strings, ignoring case
#include <wchar.h>
int
wcscasecmp( |
const wchar_t * | s1, |
const wchar_t * | s2) ; |
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)).
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.
The behaviour of wcscasecmp
() depends on the LC_CTYPE
category of the current locale.
