Description
Acquires a write lock on the object.
Implement the BeginWrite method to provide read and write locking for your object. By calling BeginWrite, a thread can change the state of the object. BeginWrite returns True if the lock was acquired successfully or False otherwise. Read and write locks are exclusive; they require that no other thread holds a read or read/write lock on the object.
