NAME

kuncd — The Kernel User Notification Center daemon.

DESCRIPTION

The Kernel User Notification Center daemon handles requests by software
executing in the kernel to display notices and alerts to the user. The
daemon also handles kernel reqeusts to execute user-space helper tools.

The daemon is launched by mach_init(8) when a request has been received
from the kernel and will exit 15 seconds after the last request has been
processed.

The daemon cannot be used directly by the user.

SIGNALS

SIGTERM This signal will result in the daemon unregistering itself from
mach_init and exiting. Once it is unregistered, it will not run
again until it is reregistered.

NAME

notifyd — notification server

SYNOPSIS

notifyd [-d] [-v] [-shm_pages npages] [-no_restart]

DESCRIPTION

notifyd is the server for the Mac OS X notification system described in
notify(3). The server is usually started automatically during system
startup, and is not run from the command line.

The -d option causes notifyd to run in a debugging mode. It will stay
attached to the terminal and print verbose log messages to the terminal.

The -v option causes notifyd to produce verbose logging information.

The -shm_pages npages option sets the number of shared memory pages used
for passive notification. The default is one page. If a value of zero
is specified, shared memory is disabled, and passive notifications are
performed using IPC between the client and the server.

The -no_restart option causes notifyd to register as a non-restartable
server with mach_init.
