When coding the IOSCDR macro, you must also decide how long you
want the macro to perform I/O before being purged. IOSCDR runs until
one of the following occurs:
- IOSCDR completes, successfully or unsuccessfully
- The interval that you specify on the TIME parameter expires
- The MIH interval for the device expires.
Note that the TIME parameter allows you to set an expiration time
that is specific to IOSCDR. The MIH interval, however, is used by
all services associated with the device.
