pthread_spin_lock()

Lock a thread spinlock

Synopsis:

#include <pthread.h>

int pthread_spin_lock( pthread_spinlock_t * spinner );

Library:

libc

Description:

The pthread_spin_lock() function locks the thread spinlock specified by spinner. If spinner isn't immediately available, pthread_spin_lock() spins until spinner can be locked.

If a thread attempts to lock a spinlock that's already locked via pthread_spin_lock() or pthread_spin_trylock() it deadlocks.

Returns:

EOK

Success.

EAGAIN

Insufficient resources available to lock spinner.

EDEADLK

The calling thread already holds spinners lock.

EINVAL

Invalid pthread_spinlock_t object spinner.
