Get the wake-up attribute of a mutex
#include <pthread.h> int pthread_mutexattr_getwakeup_np( const pthread_mutexattr_t *attr, int *wakeup );
- A pointer to the pthread_mutexattr_t object that you want to get the attribute from.
- A pointer to a location where the function can store the current value of the attribute.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_mutexattr_getwakeup_np() function gets the value of the wake-up attribute for 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 these functions' names stands for non-POSIX.
