EXIT(3F)																  EXIT(3F)

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

_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 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 and 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, and 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
