I was trying to determine the screensaver timeout via the Win32::API like so...

#!/usr/bin/perl -w
use strict;
use Win32::API;

Win32::API->Import("kernel32", "INT SPI_GETSCREENSAVETIMEOUT()"); 
my $foo = SPI_GETSCREENSAVETIMEOUT();

[download]

...but it's getting me nowhere. I get this error...

Undefined subroutine &main::SPI_GETSCREENSAVETIMEOUT called at ...

[download]

...even though a similar coding works for...

Win32::API->Import("kernel32", "int GetCurrentProcessId()");
$PID = GetCurrentProcessId();

[download]

I got the parameter from here: msdn.microsoft.com

I'd like to intelligently set the timing on my screensaver defeat script. Possibly I'd like for the script to let the user turn screensaving off for a period via SPI_SETSCREENSAVEACTIVE or some other method.
