PANIC(9)                      BSD Kernel Manual                       PANIC(9)

NAME

     panic - Bring down system on fatal error

SYNOPSIS

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

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

DESCRIPTION

     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

     The panic() function does not return.
