wcsncasecmp — compare two fixed-size wide-character strings, ignoring case
#define _GNU_SOURCE #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.
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems.
