_SHELL_CancelAppyTimeEvent

include shell.inc
VxDcall _SHELL_CancelAppyTimeEvent, <EventHandle>

Cancels subsequent calls to the callback procedure associated with the given application time event handle. Uses C calling conventions.

• No return value.

EventHandle

Handle of the application time event to cancel. The handle must have been previously returned by the _SHELL_CallAtAppyTime service.

This is not an asynchronous service.

For convenience, zero is a valid parameter value, in which case the service does nothing and returns immediately.
