Asterisk func lock
Synopsis:Attempt to obtain a named mutex
Introduced in Asterisk 1.6
Attempts to grab a named lock exclusively, and prevents other channels from
obtaining the same lock. LOCK will wait for the lock to become available.
Returns 1 if the lock was obtained or 0 on error.
NotesTo avoid the possibility of a deadlock, LOCK will only attempt to
obtain the lock for 3 seconds if the channel already has another lock.
