The function
process-sharing-unlock
is the same as process-unlock but for a "sharing" lock.
Calls to
process-sharing-unlock
should be matched by calls to process-sharing-lock. Normally with-sharing-lock is the best way to achieve this.
process-sharing-unlock
is guaranteed to successfully unlock the lock, but is not guaranteed to return, as described in Guarantees and limitations when locking and unlocking.
