typesupport handle calls

[corsaircpt]

Hi,

The code crashes in below line;

In Node.m ;

intptr_t typesupportHandle = [messageType typesupportHandle];

I am curious as to where the implementation of typesupportHandle would be and how this code ties to the msg.h.template and msg.m.templates and the rosidl_generator_objc init.py if at all. Thanks

For instance if messageType is meant to represent string for instance then what type messageType intended to be in this function and what function is typesupportHandle supposed to map to ?
