multithreading - Using a global struct with pthreads in C

WebFor pthreads, the easiest way to do this is to have threads that wake up as a result of a pthread_cond_signal () then call (inside the pthread_cond_wait () code) pthread_mutex_lock () to reacquire the lock they were holding when they blocked. However, in a monitor, this lock is usually the same lock that is used to implement mutual exclusion. Webint pthread_cond_t::waiters. Definition at line 282 of file pthread.h.
