aio_prio_delta_max

aio_prio_delta_max specifies the maximum slow-down factor (priority offset) for POSIX asynchronous I/O operations. This is the maximum priority-offset value allowed in the aio_reqprio field in the asynchronous I/O control block (aiocb structure).

Acceptable Values:

Minimum
0
Maximum
20
Default
20

Specify integer value. For more information, see Specifying Parameter Values.

Description

This parameter places a limit on how much the priority of a POSIX asynchronous I/O operation can be reduced to slow down it down. This limits the value allowed for int aio_reqprio in the asynchronous-I/O control block structure aiocb.

For more information about POSIX asynchronous I/O, see the HP-UX Reference entry aio(5).
