NAME
       scpanic - write halt message and enter emergency shutdown sequence

SYNOPSIS
       #include "/usr/src/uts/aviion/ii/isc.h"

       void    scpanic (haltcode)
       scpaniccodetype  haltcode;   /*READ ONLY*/

   where:
       haltcode   A value identifying the cause of the halt.  This value
                   will be written to the system console along with the halt
                   message.  Non-standard devices should use a halt code
                   between 0 and 511 decimal to avoid collision with
                   existing system halt codes.

DESCRIPTION
       This routine is the halt routine that you call when serious errors or
       inconsistencies are detected.  A halt message is written to the
       system console, and the emergency shutdown sequence is entered.

       The halt lock is obtained to ensure that only one processor enters
       the halt and emergency shutdown code.  If any other processors are
       running, they are stopped.

DIAGNOSTICS
   Return Value
       None.

   Errors
       None.

   Abort Conditions
       None.
