exit, _exit - terminate a process

<H2>SYNOPSIS</H2><PRE>
|
|
<STRONG>void</STRONG> <STRONG>_exit(int</STRONG> <EM>status</EM><STRONG>)</STRONG>
|
|
|

|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
<STRONG>_exit</STRONG> terminates a process with the following consequences:
|
|
|
|
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.
|
|
|
|
If the parent process of the calling process is executing a <STRONG>wait</STRONG> or
|
|
is interested in the SIGCHLD signal (Minix-vmd), then it is notified
|
|
of the calling process's termination and the low-order eight bits of
|
|
<EM>status</EM> are made available to it; see <STRONG><A HREF="../man2/wait.2.html">wait(2)</A></STRONG>.
|
|
|
|
The parent process ID of all of the calling process's existing child
|
|
processes are also set to 1. This means that the initialization
|
|
process (see <STRONG><A HREF="../man2/intro.2.html">intro(2)</A></STRONG>) inherits each of these processes as well.
|
|
|
|
Most C programs call the library routine <STRONG><A HREF="../man3/exit.3.html">exit(3)</A></STRONG>, which performs cleanup
|
|
actions in the standard I/O library before calling _<EM>exit</EM>.
|
|
|
|
|
|
</PRE>
|
|
<H2>RETURN VALUE</H2><PRE>
|
|
This call never returns.
