EXIT(2) System Calls Manual EXIT(2)NAME
exit - terminate process
SYNOPSIS
exit(status)
int status;
_exit(status)
int status;
DESCRIPTION
Exit is the normal means of terminating a process. Exit 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.
This call can never return.
The C function exit may cause cleanup actions before the final `sys exit'. The function _exit circumvents all cleanup.

exit(2) System Calls Manual exit(2)Name
_exit - terminate a process
Syntax
#include <stdlib.h>
void _exit(status)
int status;
Description
The function, terminates a calling process with the following consequences:
o All of the file descriptors open in the calling process are closed.
o If the parent process of the calling process is executing a it is notified of the calling process's termination and the low-order
eight bits of status are made available to it. For further information, see
o The parent process ID of all of the calling process's existing child processes and zombie processes are also set to 1. This means
that the initialization process inherits each of these processes as well. For further information, see
o Each attached shared memory segment is detached and the value of shm_nattach in the data structure associated with its shared memory
identifier is decremented by 1.
o For each semaphore for which the calling process has set a semadj value, (see ) that semadj value is added to the semval of the speci-
fied semaphore.
o If the process has a process, text, or data lock, an unlock is performed.
o An accounting record is written on the accounting file if the system's accounting routine is enabled. For more information, see
Calling directly circumvents all cleanup. Most C programs call the library routine which performs cleanup actions in the standard I/O
library before calling
Environment
POSIX, System V
The function differs from the System V as well as POSIX definition in that even if the calling process is a process group leader, the
SIGHUP signal is not sent to each process that has a process group ID equal to that of the calling process.
The function also differs in that the routine is declared as type int instead of type void.
See Alsofork(2), wait(2), exit(3), signal(3).
