To enable printing of debugging output, you must <tt>#define DEBUG</tt> before including plplotP.h or specify -DDEBUG in the compile line, for each file that you want to have debug output enabled. When running the program you must in addition specify <tt>-debug</tt>. This allows debugging output to tailored to many different circumstances but otherwise be fairly unobtrusive. Note, any file that actually uses <tt>pldebug()</tt> must also define <tt>NEED_PLDEBUG</tt> before the <tt>plplotP.h</tt> include. This is to eliminate warnings caused by those files in which this is defined but never referenced.</li> <li><tt>dbug_enter(a)</tt> : This function will put the string <pre> entered a (<strong>FILE</strong>, line <strong>LINE</strong>)\n</pre> to <tt>stderr</tt> if the macro <tt>DEBUG_ENTER</tt> is set.</li> </ul> <p>The content of this page is available under the <a class="" href="http://www.gnu.org/copyleft/fdl.html" rel="nofollow">GNU Free Documentation License 1.2</a>.</p></div>Alan W.
