Member Function Documentation

void CVD::Synchronized::lock

(

)

const

Acquire the lock; this blocks until the lock is available.

This can be called multiple times by the same thread without deadlocking. Each call should have a matching unlock() call.

void CVD::Synchronized::unlock

(

)

const

Release the lock.
