<h3>Name</h3>
_exit - terminate process

<h3>Library</h3>
Standard C Library (libc, -lc)

<h3>Synopsis</h3>
#include &lt;unistd.h&gt;<br>
<br>
void<br>
_exit(int <em>exitcode</em>);

<h3>Description</h3>

Cause the current process to exit. The exit code <em>exitcode</em> is
reported back to other process(es) via the 
<A HREF=waitpid.html>waitpid()</A> call. The process id of the exiting
process should not be reused until all processes interested in
collecting the exit code with waitpid have done so. (What "interested"
means is intentionally left vague; you should design this.)

<h3>Return Values</h3>
_exit does not return.
