wcscmp

Compares two wide-character strings. It returns an integer that indicates if the strings are different, and how they differ.

#include  <wchar.h>

int wcscmp  (const wchar_t *wstr_1, const wchar_t
            *wstr_2);

This function compares the wide characters in wstr_ 1 with those in wstr_2. If the characters differ, the function returns:

An integer less than 0, if the codepoint of the first differing character in wstr_1 is less than the codepoint of the corresponding character in wstr_2
An integer greater than 0, if the codepoint of the first differing character in wstr_1 is greater than the codepoint of the corresponding character in wstr_2

If the wide-characters strings are identical, the function returns zero.

Unlike the wcscoll function, the wcscmp function compares the string based on the binary value of each wide character.

< 0	Indicates that wstr_ 1 is less than wstr_2.
= 0	Indicates that wstr_1 equals wstr_ 2.
> 0	Indicates that wstr_1 is greater than wstr_2.
