wcsncmp — compare two fixed-size wide-character strings
#include <wchar.h>
int
wcsncmp( |
const wchar_t * | s1, |
const wchar_t * | s2, | |
size_t | n) ; |
The wcsncmp
() function is
the wide-character equivalent of the strncmp(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. In each string, the comparison extends only up to the
first occurrence of a L'\0' character, if any.
The wcsncmp
() function
returns zero if the wide-character strings at s1
and s2
, truncated to at most length
n
, are equal. It
returns an integer greater than zero if at the first
differing position i
(i
< n
), the corresponding
wide-character s1[i]
is greater than
s2[i]
. It returns
an integer less than zero if at the first differing position
i
(i
< n
), the corresponding
wide-character s1[i]
is less than s2[i]
.
