The scoped locking pattern.
scoped_lock(spin_rw_mutex &m, bool write=true)
Acquire lock on given mutex.
scoped_lock()
Construct lock that has not acquired a mutex.
~scoped_lock()
Release lock (if lock is held).
void acquire(spin_rw_mutex &m, bool write=true)
Acquire lock on given mutex.
spin_rw_mutex * mutex
The pointer to the current mutex that is held, or NULL if no mutex is held.
