Howdy fellow monks! I've been fighting with perlxs and a C++ class for a bit now. I've managed to get the whole thing to compile, but I'm having a bit of trouble understanding how to use it now that I've got it. The perldoc for perlxs seems to say how to set up the .xs file, but not how to call the functions. For instance, I've added the following to the basic .xs file: 
float 
Point_2D::x()

    CODE:
    RETVAL=THIS->x();
    OUTPUT:
    RETVAL
    
void
Point_2D::set_x(arg)
    float arg
    
    CODE:
    THIS->x(arg);
    
    
void
Point_2D::DESTROY()

    CODE:
    delete THIS;

Point_2D *
Point_2D::new()

    CODE:
    RETVAL = new Point_2D();
    OUTPUT:
    RETVAL

And I've made a test script that looks like this: 
#!/usr/sbin/perl -w

use ExtUtils::testlib;
use Point_2D;

my $pt;
my $output;

print "making object\n";
$pt = Point_2D::new(Point_2D);
print "setting value\n";
Point_2D::set_x($pt,1.2);
print "retrieving value\n";
$output = Point_2D::x($pt);
print "output = ",$output;

The output of which is:
making object
