panic(9r) [osf1 man page]

panic(9r)																 panic(9r)

NAME

       panic - General: Causes a system crash

SYNOPSIS

       void panic(
	       char *message );

ARGUMENTS

       Specifies the message you want the panic routine to display on the console terminal.

DESCRIPTION

       The  panic  routine causes a system crash, usually because of fatal errors. It sends to the console terminal and error logger the specified
       message and, possibly, other system-dependent information (for example, register dumps). It also causes a crash dump to be generated. After
       displaying the message, panic reboots the system if the console environment variables are set appropriately.

RETURN VALUES

       None

NAME

       ddi_in_panic - determine if system is in panic state

SYNOPSIS

       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       int ddi_in_panic(void);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

DESCRIPTION

       Drivers	controlling devices on which the system may write a kernel crash dump in the event of a panic can call ddi_in_panic() to determine
       if the system is panicking.

       When the system is panicking, the calls of functions scheduled by timeout(9F) and ddi_trigger_softintr(9F) will never  occur.  Neither  can
       delay(9F) be relied upon, since it is implemented via  timeout(9F).

       Drivers that need to enforce a time delay such as  SCSI bus reset delay time must busy-wait when the system is panicking.

RETURN VALUES

       ddi_in_panic() returns  1 if the system is in panic,  or   0 otherwise.

CONTEXT

       ddi_in_panic() may be called from any context.

SEE ALSO
