16-bit unsigned integer by value (required)
Contains the priority class in which the new process is scheduled
(AS, BS, CS, DS, ES), computed in the following manner:
(ASCII of first character * 256) +
(ASCII of second character)
|
The integer equivalents are:
AS = 16,723
BS = 16,979
CS = 17,235
DS = 17,491
ES = 17,747
|
Aborts the calling process if priorityclass exceeds the maximum
allowable priority class of the rescheduled process or specifies an
invalid priority class.
Specify any priority class except AS, if in user mode; this function is
limited by the maximum priority assigned to the account by the system
manager. If in privileged mode, processes can be scheduled into all
subqueues including AS. Processes in the linear queues, AS or BS, do
not give up the CPU voluntarily; it could loop indefinitely and
prevent other processes from accessing the CPU.
If in privileged mode, specify the priorityclass parameter as
an absolute priority by xA, where x is an 8-bit priority
number and A is the ASCII character A. For example, to request
a priority class of 31 in the master queue, set priorityclass to
%017501. An absolute priority must be specified in order to overcome
the MAXPRI setting of an account.
Default: The priority class of the calling process
