Asterisk func lock

Synopsis:

Attempt to obtain a named mutex
Introduced in Asterisk 1.6

Description:

LOCK(<lockname>)

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.

Notes

To avoid the possibility of a deadlock, LOCK will only attempt to
obtain the lock for 3 seconds if the channel already has another lock.
