Set the wake-up attribute of a mutex
#include <pthread.h> int pthread_mutexattr_setwakeup_np( pthread_mutexattr_t *attr, int wakeup );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_mutexattr_setwakeup_np() function sets the wake-up attribute of the given mutex. If this attribute is enabled, a thread can call pthread_mutex_wakeup_np() to unblock any threads that are waiting for the mutex.
The np in this function's name stands for non-POSIX.
