RETURN RESOURCE

Returns resource for any instance that has requested and is waiting for the resource. If the resource is not requested by another instance, it is left active. If resource used is not required by any other instance, it is left active.

WAIT

The command is executed synchronously. The function waits until the requested action is complete before returning to the application.

NOTIFY

The command is executed asynchronously, allowing control to be returned immediately to the application. When the requested action is complete, an MM_MCINOTIFY message is sent to the application window procedure.

Remarks

The RELEASE command releases exclusive use of the physical resources by the device context.
