Functions / Entering and Leaving Interrupt Time

OTLeaveInterrupt

Notifies Open Transport that you are done calling Open Transport functions from an interrupt.

C INTERFACE

void OTLeaveInterrupt(void)

C++ INTERFACES

None. C++ applications use the C interface to this function.

DESCRIPTION

The OTLeaveInterrupt function informs Open Transport that you are no longer calling Open Transport from within an interrupt. You call this function after you call the last Open Transport function you want to call from within the interrupt, but before you return to system task time.

SPECIAL CONSIDERATIONS

Do not make this call without having already called the OTEnterInterrupt function.

On the 68000-family of Macintosh computers, you must be sure that your A5 world is set correctly before making this call (that is, you must set it to the same value it had when you called the InitOpenTransport or the InitOpenTransportUtilities function).

SEE ALSO

To notify Open Transport that you are about to call an Open Transport function from an interrupt, use the OTEnterInterrupt function (page 7-19).

For further discussion, see the section "Entering and Leaving Interrupt Processing," beginning on page 7-6.
