STRCOLL(3)								 1								STRCOLL(3)

strcoll - Locale based string comparison

SYNOPSIS
       int strcoll (string  $str1, string  $str2)

DESCRIPTION
	Note that this comparison is case sensitive, and unlike strcmp(3) this function is not binary safe.

       strcoll(3)  uses  the  current  locale  for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to str-
       cmp(3).

PARAMETERS
	      o $str1
		- The first string.

	      o $str2
		- The second string.

RETURN VALUES
	Returns < 0 if $str1 is less than $str2; > 0 if $str1 is greater than $str2, and 0 if they are equal.
