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-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].
