NAME

wcsncmp - compare two fixed-size wide-character strings

SYNOPSIS

#include s1, const wchar_t *s2, size_t n);

DESCRIPTION

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.

RETURN VALUE

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?.
