WCSNCMP(3)                                                              Linux Programmer's Manual                                                             WCSNCMP(3)

NAME
       wcsncmp - compare two fixed-size wide-character strings

SYNOPSIS
       #include <wchar.h>

       int wcsncmp(const wchar_t *s1, const wchar_t *s2, 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-charac‐
       ter 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].
