strcoll(3)              Library Functions Manual              strcoll(3)

NAME         top

       strcoll - compare two strings using the current locale

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <string.h>

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

DESCRIPTION         top

       The strcoll() function compares the two strings s1 and s2.  It
       returns an integer less than, equal to, or greater than zero if
       s1 is found, respectively, to be less than, to match, or be
       greater than s2.  The comparison is based on strings interpreted
       as appropriate for the program's current locale for category
       LC_COLLATE.  (See setlocale(3).)

RETURN VALUE         top

       The strcoll() function returns an integer less than, equal to, or
       greater than zero if s1 is found, respectively, to be less than,
       to match, or be greater than s2, when both are interpreted as
       appropriate for the current locale.
