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

NAME         top

       wcsncmp - compare two fixed-size wide-character strings

SYNOPSIS         top

       #include <wchar.h>

       int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);

DESCRIPTION         top

       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         top

       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].
