AUnblock removes a temporary block on events that was imparted by ABlock. The three forms of AUnblock are given the following names:
| Editor’s note: "imparted" doesn’t seem to be the right word. Suggest to change it to "created". |
| a) | L evclass | Selective AUnblock | |
| b) | (L evclass) | Exclusive AUnblock | |
| c) | Empty argument list: | AUnblock All |
In the Selective AUnblock, the named event classes are unblocked as described below. In the Exclusive AUnblock, all event classes except the named event classes are unblocked as described below. In the AUnblock All, all event classes are unblocked as described below.
When an event class is unblocked, the internal counter for the event class (see ABlock) is decremented, unless it is already zero (the counter may not be negative). If the counter is zero, the temporary block, if any, on the event class is removed. Pending events (see ABlock), if any, occur in the order in which they arrived. Blocks are removed only for the process executing the AUnblock command. It is not an error to unblock events which are not currently blocked.
