<h2><a name="setjmp" id="setjmp">setjmp</a></h2>
<div class="level2">
<p>
Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <csetjmp></span>
<span class="kw4">int</span> setjmp<span class="br0">(</span> jmp_buf envbuf <span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The setjmp() function saves the system stack in envbuf for use by a later call
to longjmp(). When you first call setjmp(), its return value is zero. Later,
when you call longjmp(), the second argument of longjmp() is what the return
value of setjmp() will be. Confused? Read about longjmp().
