### strcoll -- Compare Strings

Format

>     #include <string.h>
>     int strcoll(const char *string1, const char *string2);

Language Level: ANSI, XPG4
strcoll compares two strings using the collating sequence specified by the program's locale.

Return Value
strcoll returns a value indicating the relationship between the strings, as listed below:

Value | Meaning
Less than 0 | string1 less than string2
0 | string1 equivalent to string2
Greater than 0 | string1 greater than string2

Example
This example compares the two strings passed to main.

    #include <stdio.h>
    #include <string.h>

    int main(int argc, char ** argv)
    {
      int  result;

      if ( argc != 3 )
      {
        printf( "Usage: %s string1 string2\n", argv[0] );
      }
      else
      {

        result = strcoll( argv[1], argv[2] );

        if ( result == 0 )
          printf( "\"%s\" is identical to \"%s\"\n", argv[1], argv[2] );
        else if ( result < 0 )
          printf( "\"%s\" is less than \"%s\"\n", argv[1], argv[2] );
        else
          printf( "\"%s\" is greater than \"%s\"\n", argv[1], argv[2] );
      }

      /*****************************************************************
         If the program is passed the following arguments:
         "firststring" "secondstring"

         The output should be:
         "firststring" is less than "secondstring"
