<h1>uip/lc-addrlabels.h File Reference</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
Implementation of local continuations based on the "Labels as values" feature of gcc.
<p>
<dl compact><dt><b>Author:</b></dt><dd>Adam Dunkels &lt;<a href="mailto:adam@sics.se">adam@sics.se</a>&gt;</dd></dl>
This implementation of local continuations is based on a special feature of the GCC C compiler called "labels as values". This feature allows assigning pointers with the address of the code corresponding to a particular C label.<p>
For more information, see the GCC documentation: <a href="http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html">http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html</a><p>
Thanks to dividuum for finding the nice local scope label implementation.
