The implementation is based on the fact that switch() statements are able to jump directly into the bodies of control structures such as if() or while() statmenets.<p> 26This implementation borrows heavily from Simon Tatham's coroutines implementation in C: <a href="http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html">http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html</a> 27<p> 28Definition in file <a class="el" href="a00190.html">lc-switch.h</a>. 29<p> 30 31<p> 32<a href="a00190.html">Go to the source code of this file.</a><table border="0" cellpadding="0" cellspacing="0"> 33<tr><td></td></tr> 34<tr><td colspan="2"><br><h2>Defines</h2></td></tr> 35<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="g44311ecc30759ca38b4069182247bdae"></a><!-- doxytag: member="lc-switch.h::__LC_SWTICH_H__" ref="g44311ecc30759ca38b4069182247bdae" args="" --> 36#define </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#g44311ecc30759ca38b4069182247bdae">__LC_SWTICH_H__</a></td></tr> 37 38<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="g2c1bb4fa6d7a6ff951a41c73fc721109"></a><!-- doxytag: member="lc-switch.h::LC_INIT" ref="g2c1bb4fa6d7a6ff951a41c73fc721109" args="(s)" --> 39#define </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#g2c1bb4fa6d7a6ff951a41c73fc721109">LC_INIT</a>(s) s = 0;</td></tr> 40 41<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="g1ec8b8f4710dce1fa7fb87d3a31541ae"></a><!-- doxytag: member="lc-switch.h::LC_RESUME" ref="g1ec8b8f4710dce1fa7fb87d3a31541ae" args="(s)" --> 42#define </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#g1ec8b8f4710dce1fa7fb87d3a31541ae">LC_RESUME</a>(s) switch(s) { case 0:</td></tr> 43 44<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="gd8eec328a4868d767f0c00c8d1c6cfc1"></a><!-- doxytag: member="lc-switch.h::LC_SET" ref="gd8eec328a4868d767f0c00c8d1c6cfc1" args="(s)" --> 45#define </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#gd8eec328a4868d767f0c00c8d1c6cfc1">LC_SET</a>(s) s = __LINE__; case __LINE__:</td></tr> 46 47<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="gca51ceb2f5d855dfde55bcedf8d3b92d"></a><!-- doxytag: member="lc-switch.h::LC_END" ref="gca51ceb2f5d855dfde55bcedf8d3b92d" args="(s)" --> 48#define </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#gca51ceb2f5d855dfde55bcedf8d3b92d">LC_END</a>(s) }</td></tr> 49 50<tr><td colspan="2"><br><h2>Typedefs</h2></td></tr> 51<tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="g3983e0c026396d5c4506779d770007ba"></a><!-- doxytag: member="lc-switch.h::lc_t" ref="g3983e0c026396d5c4506779d770007ba" args="" --> 52typedef unsigned short </td><td class="memItemRight" valign="bottom"><a class="el" href="a00155.html#g3983e0c026396d5c4506779d770007ba">lc_t</a></td></tr> 53 54</table> 55<hr size="1"><address style="align: right;"><small>Generated on Mon Jun 12 10:23:01 2006 for uIP 1.0 by 56<a href="http://www.doxygen.org/index.html"> 57<img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.4.6 </small></address> 58</body> 59</html> 60
