Name
       strcoll - string collation comparison

Syntax
       int strcoll (s1, s2)
       char *s1, *s2;

Description
       The function returns an integer less than, equal to, or greater than zero depending on whether the string pointed to by s1 is lexicographi-
       cally less than, equal to, or greater than the string pointed to by s2.

       The function performs the comparison by using the collating information defined in the program's locale, category

       In the C locale, characters collate as if they are unsigned.  In all cases works as if were called on s1 and s2,  and  was  called  on  the
       resulting strings.
