/*  set_vector

 *

 *  This routine installs an interrupt vector on UNIX.

 *

 *  INPUT:

 *    handler - interrupt handler entry point

 *    vector  - vector number

 *    type    - 0 indicates raw hardware connect

 *              1 indicates RTEMS interrupt connect

 *

 *  RETURNS:

 *    address of previous interrupt handler
