I have malloc'd a whole mess of data in an NSOperation instance. I have a pointer:

data = malloc(humungous_amounts_of_god_knows_what);
uint8_t* data;

How do I package this up as an NSData instance and return it to the main thread? I am assuming that after conversion to an NSData instance I can simply call:

free(data);

Yes?

Also, back on the main thread how do I retrieve the pointer?

Thanks,
Doug
