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 null wide character (L'\0'), 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].
For an explanation of the terms used in this section, see attributes(7).
