What do __VOID and __INT expand to? I can't seem to find their definitions. They put theStatus outside of any function (i.e. it's not on the stack) so that makes me think they're something like:

Code:
#define __VOID(X) ((void*)(&X))

(and similarly for int)

This would also give correct code, and would make the pointers point to the return value (good practice) instead of being tread as the return value (awful practice). Give it a go - the compiler will like it a lot more!

NAME
pthread_exit - terminate the calling thread SYNOPSIS
#include <pthread.h> void pthread_exit(void *retval); DESCRIPTION
pthread_exit terminates the execution of the calling thread. All cleanup handlers that have been set for the calling thread with pthread_cleanup_push(3) are executed in reverse order (the most recently pushed handler is executed first). Finalization functions for thread-specific data are then called for all keys that have non- NULL values associated with them in the calling thread (see pthread_key_create(3)). Finally, execution of the calling thread is stopped. The retval argument is the return value of the thread. It can be consulted from another thread using pthread_join(3). RETURN VALUE
The pthread_exit function never returns. AUTHOR
