[ac7d5ef0]1/*  set_vector
2 *
3 *  This routine installs an interrupt vector on the HP PA-RISC simulator.
4 *
5 *  INPUT:
6 *    handler - interrupt handler entry point
7 *    vector  - vector number
8 *    type    - 0 indicates raw hardware connect
9 *              1 indicates RTEMS interrupt connect
10 *
11 *  NOTE 'type' is ignored on hppa; all interrupts are owned by RTEMS
12 *
13 *  RETURNS:
14 *    address of previous interrupt handler
