It seems you have two problems - one is mixing C with ObjC, and the other 
one is mixing pthreads with NSThread.

I recommend attacking one problem at a time.

Mixing C and ObjC is usually simple - you can put your ObjC code into a
library (or module) and load/link/call it with/from the C code.

Mixing pthreads with NSThreads shouldn't be difficult.

When you start accessing ObjC from a pthread you yourself (or a
pthread-based threaded library) created, you need to call
GSRegisterCurrentThread() before using any ObjC code.

Once you're done with your ObjC code and you want to deregister the thread 
with the ObjC machinery, you can call GSUnregisterCurrentThread().

I recommend attacking one problem at a time though.
