/*  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
