Detailed Description

Provides a read-write spin lock.

You may either create a a new lock with qev_lock_new/qev_lock_free, or you can allocate it statically/as part of another structure, so long as it's initialized to 0 on creation.

Note

All locking operations issue full memory barriers.

typedef guint32 qev_lock_t

Locks are implemented without much ado.

Literally, just declare this statically or in a larger structure, make sure it's 0, and baby, you got a lock goin'!
