|
|
// priorities might be used by VxWorks tasks that run "above" QP active
|
|
// objects.

//
|
|
// Because the VxWorks priority numbering is "upside down" compared

|
// to the QP priority numbering, the VxWorks priority for an active object
|

// vx_prio = QF_VX_PRIO_OFFSET + QF_MAX_ACTIVE - qp_prio
