The function needs to return 0; returning a non-zero value stops the iteration.

Try:

#!perl

use Mac::MoreFiles;

FSpIterateDirectory(":", 0, DoThis, "Information returned: ");

sub DoThis {
	print $_[1], $_[0], "\n";
	return 0;
}

I found this out by looking at the Shuck documentation and looking at the
Iterate.t file.

Note that the documentation is wrong: the function is not called as

    $quit = &$filterFunction(YOURDATAPTR, SPEC);

but as

    $quit = &$filterFunction(SPEC, YOURDATAPTR);
