I am trying to determine the binary type of various files using the Win32 API GetBinaryType. For some reason the code below does not quite work. It doesn't return any value. Any suggestions why? 
#!perl
use strict;
use Win32::API;
my $filename="C:\\WINDOWS\\system32\\notepad.exe";
my $GetBinaryType ||= new Win32::API("kernel32", "GetBinaryTypeA", ['P
+','P'],'N') || die $^E;
my $type = ' 'x5;
my $Bool = $GetBinaryType->Call($filename, $type);
print " $Bool, ($filename, $type)\n";
#$type should return one of the following values, but it returns nothi
+ng. :(
#     0   A Win32 based application
#     1   An MS-DOS based application
#     2   A 16-bit Windows based application
#     3   A PIF file that executes an MS-DOS based application
#     4   A POSIX based application
#     5   A 16-bit OS/2 based application
