This service call returns various statuses of the message buffer indicated by mpfid.
wtskid
Returned to wtskid is the ID number of the task at the top of a memory block waiting queue (the first queued
task). If no tasks are kept waiting, TSK_NONE is returned.
fblkcnt
The number of free memory blocks in the specified memory pool is returned.
If this service call is to be issued from task context, use rel_mpf; if issued from non-task context, use irel_mpf.
