NAME

wcsncmp - compare two fixed-size wide-character strings

LIBRARY

Standard C library ( libc , -lc )

SYNOPSIS

#include <wchar.h>

int wcsncmp(const wchar_t s1 [. n ], const wchar_t s2 [. n ], size_t n );

DESCRIPTION

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.

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] .

ATTRIBUTES
