acquire
Description:
Tries to become the owner of the specified context.
If some other thread is the owner of the context, returns false immediately. Ownership is properly recursive: the owner can require ownership again and will release ownership when release is called as many times as acquire.
You must be the owner of a context before you can call prepare, query, check , dispatch.
Parameters:

Returns:
true if the operation succeeded, and this thread is now the owner of this . |
