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.
