NAME

     panic — bring down system on fatal error

SYNOPSIS

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

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

     void
     vpanic(const char *fmt, va_list ap);

DESCRIPTION

     The panic() and vpanic() functions terminate the running system.  The message fmt is a
     printf(3) style format string.  The message is printed to the console and the location
     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.
