It compares the wide-character string pointed to by .I s1 and the wide-character string pointed to by .IR s2 . .SH RETURN VALUE The .BR wcscmp () function returns zero if the wide-character strings at .I s1 and .I s2 are equal. It returns an integer greater than zero if at the first differing position .IR i , the corresponding wide-character .I s1[i] is greater than .IR s2[i] . It returns an integer less than zero if at the first differing position .IR i , the corresponding wide-character .I s1[i] is less than .IR s2[i] . .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lbx lb lb l l l.
