exit

EXIT(2) 							System Calls Manual							   EXIT(2)

NAME

       exit, _exit - terminate a process

SYNOPSIS

       void _exit(int status)

DESCRIPTION

       _exit terminates a process with the following consequences:

	      All  of the descriptors open in the calling process are closed.  This may entail delays, for example, waiting for output to drain; a
	      process in this state may not be killed, as it is already dying.

	      If the parent process of the calling process is executing a wait or is interested in the SIGCHLD	signal	(Minix-vmd),  then  it	is
	      notified of the calling process's termination and the low-order eight bits of status are made available to it; see wait(2).

	      The  parent  process ID of all of the calling process's existing child processes are also set to 1.  This means that the initializa-
	      tion process (see intro(2)) inherits each of these processes as well.

       Most C programs call the library routine exit(3), which performs cleanup actions in the standard I/O library before calling _exit.

RETURN VALUE

       This call never returns.

SEE ALSO

       fork(2), sigaction(2), wait(2), exit(3).
