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.
