wcsncasecmp — compare two fixed-size wide-character strings, ignoring case
#include <wchar.h>
int
wcsncasecmp( |
const wchar_t * | s1, |
const wchar_t * | s2, | |
size_t | n) ; |
The wcsncasecmp
() function
is the wide-character equivalent of the strncasecmp(3) function. It
compares the wide-character string pointed to by s1
and the wide-character
string pointed to by s2
, but at most n
wide characters from each
string, ignoring case differences (towupper
(3), towlower(3)).
The wcsncasecmp
() function
returns zero if the wide-character strings at s1
and s2
, truncated to at most length
n
, are equal except
for case distinctions. It returns a positive integer if
truncated s1
is
greater than truncated s2
, ignoring case. It returns a
negative integer if truncated s1
is smaller than truncated
s2
, ignoring
case.
The behaviour of wcsncasecmp
() depends on the LC_CTYPE
category of the current locale.
