Unblock threads waiting on a condition
#include <pthread.h> int pthread_cond_broadcast( pthread_cond_t* cond );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_cond_broadcast() function unblocks all threads currently blocked on the condition variable cond. All affected blocked threads become runnable and are scheduled using the usual scheduling rules, which means the order in which these threads are unblocked (or woken up) is different than the order in which they were blocked.
