#include <pthread.h> int pthread_spin_unlock( spinlock_t * spinner );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_spin_unlock() function unlocks the thread spinlock specified by spinner, which was locked with pthread_spin_lock() or pthread_spin_trylock().
If there are threads spinning on spinner, the spinlock becomes available, and an unspecified thread acquires the lock.
