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 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].
