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].

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wcsncmp() function is thread-safe.

CONFORMING TO
       C99.
