.Dt PANIC 9
.Os
.Sh NAME
.Nm panic
.Nd Bring down system on fatal error
.Sh SYNOPSIS
.Fd #include <sys/types.h>
.Fd #include <sys/systm.h>
.Ft void
.Fn panic "const char *fmt, ..."
.Sh DESCRIPTION
The
.Fn panic
function terminates the running system. The message
.Fa fmt
is a
.Xr printf 3
style format string. The message is printed to the console and the location
.Fa panicstr
is set to the address of the message text for retrieval from the OS
core dump.
.Pp
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.
.Pp
If
.Fn panic
is called twice (from the disk sync routines, for example) the system is
rebooted without syncing the disks.
.Sh RETURN VALUES
The
.Fn panic
function does not return.
