EXIT(3F)																  EXIT(3F)

NAME
exit - terminate process with status SYNOPSIS
subroutine exit (status) integer status DESCRIPTION
Exit flushes and closes all the process's files, and notifies the parent process if it is executing a wait. The low-order 8 bits of status are available to the parent process. (Therefore status should be in the range 0 - 255) This call will never return. The C function exit may cause cleanup actions before the final `sys exit'. FILES

NAME
_exit -- terminate the calling process SYNOPSIS
#include <unistd.h> void _exit(int status); DESCRIPTION
The _exit() function terminates a process, with the following consequences: o All of the descriptors that were 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. o If the parent process of the calling process has an outstanding wait call or catches the SIGCHLD signal, it is notified of the calling process's termination; the status is set as defined by wait(2). o The parent process-ID of all of the calling process's existing child processes are set to 1; the initialization process (see the DEFINI- TIONS section of intro(2)) inherits each of these processes. o If the termination of the process causes any process group to become orphaned (usually because the parents of all members of the group have now exited; see ``orphaned process group'' in intro(2)), and if any member of the orphaned group is stopped, the SIGHUP signal and the SIGCONT signal are sent to all members of the newly-orphaned process group. o If the process is a controlling process (see intro(2)), the SIGHUP signal is sent to the foreground process group of the controlling ter- minal. All current access to the controlling terminal is revoked. Most C programs call the library routine exit(3), which flushes buffers, closes streams, unlinks temporary files, etc., before calling _exit(). RETURN VALUE
_exit() can never return. SEE ALSO
fork(2), sigaction(2), wait(2), exit(3) STANDARDS
The _exit function is defined by IEEE Std 1003.1-1988 (``POSIX.1''). 4th Berkeley Distribution June 4, 1993 4th Berkeley Distribution
