Wait, no, you really do want the name, don't you.  You refer to
"module.0" to get the module structure pointer (if I'm reading the code
right), but as you have that pointer already, why can't you just use
module->name there as well as you have a pointer to a valid module
structure that has the name already embedded in it.

still confused,
