Destroy a thread spinlock
#include <pthread.h>
int pthread_spin_destroy(
pthread_spinlock_t * spinner );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_spin_destroy() function destroys the thread spinlock spinner, releasing its resources.
Once you've destroyed the spinlock, don't use it again until you've reinitialized it by calling pthread_spin_init().
Calling pthread_spin_destroy() gives undefined results when a thread has spinner locked or when spinner isn't initialized.
