C - control reaches end of non-void function
Returning NULL is fine, and is the normal way. Nothing will use the return value unless you write code to use it. NULL is a valid value for void *, and if you don't care what that value is, then the only thing that matters is that it's a valid one.
try something like this:
#include <pthread.h>void* you_func( void* param ) { // do stuff here ... // and terminates as follows: pthread_exit( NULL );}hope that helps you.
