NAME    [Toc]    [Back]

     panic - Bring down system on fatal error

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <sys/systm.h>

     void
     panic(const char *fmt, ...);

DESCRIPTION    [Toc]    [Back]

     The panic() function makes  the  OpenBSD  system  terminate.
The message fmt
     is  a printf(9) style format string.  The message is printed
to the console
 and the location pointed to by the global char  pointer
panicstr is
     set  to  the  address of the message text for retrieval from
the OS core
     dump.

     If the kernel debugger is installed control is passed to it,
otherwise an
     attempt  to  save a core dump of the OS to a configured dump
device is
     made.

     If panic() is called twice (from the disk sync routines, for
example) the
     system is rebooted without syncing the disks.

RETURN VALUES    [Toc]    [Back]

     The panic() function does not return.
