It compares the .IR n wide-characters starting at .I s1 and the .I n wide-characters starting at .IR s2 . .SH RETURN VALUE The .BR wmemcmp () function returns zero if the wide-character arrays of size .I n at .IR s1 and .I s2 are equal. It returns an integer greater than zero if at the first differing position .I i .RI ( i " <" .IR n ), 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 .I i .RI ( i < .IR n ), 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; lb lb lb l l l.
