Determining if a subroutine is defined...

[Michael Dube]

Hi,

I have a script that uses require to include additional perl scripts at
runtime.  I would like to call a function if and only if that function is
defined in the required module.  How would this be done?  Would the define()
function work?  Here's some pseudo of what I intend... any ideas?

require runtime.pl;

if (defined(runtimefunction)) {
        runtimefunction(args);
}
