pthread_equal - compare two thread identifiers
#include <pthread.h> int pthread_equal(pthread_t thread1, pthread_t thread2);
pthread_equal determines if two thread identifiers refer to the same thread. A non-zero value is returned if thread1 and thread2 refer to the same thread. Otherwise, 0 is returned.
