[techspeak] During the execution of a procedural language, one is
|
||
said to <span class="firstterm">unwind the stack</span> from a
|
||
called procedure up to a caller when one discards the stack frame and any
|
||
number of frames above it, popping back up to the level of the given
|
||
caller. In C this is done with <b class="command">longjmp</b>/<b class="command">setjmp</b>, in
|
||
LISP or C++ with <b class="command">throw/catch</b>. See also

|
||
bunch of problems: “<span class="quote">Oh heck, let's do lunch. Just a second while I
|
||
unwind my stack.</span>”</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="unswizzle.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../U.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="unwind-protect.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">unswizzle </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> unwind-protect</td></tr></table></div></body></html>
