pthread_t is an opaque type defined by the POSIX standard. You may not make any assumptions about what it contains and what can be assigned to it. Platforms are allowed to implement this in any way then see fit - a typedef to an integral type, a more complex struct, a pointer to smth, ...

If PTHREAD_NULL is defined, then it may be used as a NULL-kind of value. But if it is not defined... I don't think you should write to or read from a pthread_t variable without using pthread_* functions.
