strcoll() -- compare two strings using LC

SYNOPSIS

#include <string.h>

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

DESCRIPTION

The strcoll() function compares the string pointed to by s1 to the string pointed to by s2. Both s1 and s2 are interpreted as appropriate for the LC_COLLATE category of the current locale.

PARAMETERS

s1: Is the null-terminated string to compare.
s2: Is the null-terminated string to compare.

The function strcoll() returns a positive integer if string s1 is lexically greater than string s2; zero if the two strings are identical; and a negative integer if string s1 is lexically less than string s2, as defined by the current locale.
