Summary
Increases the MeteredSection's count.
Pascal
public function Leave(ReleaseCount: Longint): Boolean; overload;
public function Leave(ReleaseCount: Longint; out PrevCount: Longint): Boolean; overload;
Parameters
| Parameters | Description |
| ReleaseCount: Longint | Specifies the number of the metered section's slots to release. The value must be greater than zero. If the specified amount would cause the metered section's count to exceed the maximum number of available slots specified during creation of the metered section, the number of available slots is not changed and the function returns False. |
| out PrevCount: Longint | 32-bit Longint which receives the previous metered section open slot count. |
Return Value
If the function succeeds the result is True, otherwise the result is False.
Description
The LeaveMeteredSection function increases the number of available slots of a metered section by a specified amount but never increases past the maximum count as specified during construction. As a result of incrementing the count one or more waiting threads may be released from their wait state. Note that incrementing the count is not thread bound. That is, all threads may call Leave even though they never called Enter.
