AIFPORTINT

record by reference (required)

Returns the overall status of the call. A zero indicates a successful call. A negative value indicates an error in the overall call. A positive value indicates a warning. Refer to appendix A for meanings of status values.

Record type: status_type (Refer to appendix B.)

32-bit signed integer array by reference (required)

Passes an array of integers that contain a list of port IDs whose handlers will be enabled or disabled. This array MUST be terminated with a zero. Each port ID must be an asynchronous port that has been created by the caller. If any port ID is invalid, then NONE of the ports will have their interrupt state changed.

Boolean array by reference (required)

An array of Booleans that specify the new port interrupt handling states that are the result of this call. A value of TRUE enables interrupt handling for the corresponding port ID in the port_list, while FALSE disables interrupt handling on a port. This array must contain as many elements as are contained in port_list.

Boolean array by reference (optional)

An array of booleans, that upon return from a successful call contains a value of TRUE for each port in port_list that had interrupts enabled prior to this call, and FALSE for each port that had interrupts disabled. This array must contain as many elements as are contained in port_list. If the call fails because of an invalid port ID and this array was passed, a value of FALSE is returned for each port that was not previously created by the caller.

Default: nil
