wcscmp(3) Library Functions Manual wcscmp(3)

NAME top

   wcscmp - compare two wide-character strings

LIBRARY top

   Standard C library (_libc_, _-lc_)

SYNOPSIS top

   **#include <wchar.h>**

   **int wcscmp(const wchar_t ***_s1_**, const wchar_t ***_s2_**);**

DESCRIPTION top

   The **wcscmp**() function is the wide-character equivalent of the
   [strcmp(3)](../man3/strcmp.3.html) function.  It compares the wide-character string pointed
   to by _s1_ and the wide-character string pointed to by _s2_.

RETURN VALUE top

   The **wcscmp**() function returns zero if the wide-character strings
   at _s1_ and _s2_ are equal.  It returns an integer greater than zero
   if at the first differing position _i_, 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_, the corresponding
   wide-character _s1[i]_ is less than _s2[i]_.
