In particular, the use of most GL calls is unsafe before the first window is opened.</p> </div> <p>The module is too large to document here in its entirety, but the following should help you to get started. The parameter conventions for the C functions are translated to Python as follows:</p> <ul> <li><p>All (short, long, unsigned) int values are represented by Python integers.</p></li> <li><p>All float and double values are represented by Python floating point numbers. In most cases, Python integers are also allowed.</p></li> <li><p>All arrays are represented by one-dimensional Python lists. In most cases, tuples are also allowed.</p></li> <li><p>All string and character arguments are represented by Python strings, for instance, <code class="docutils literal notranslate"><span class="pre">winopen('Hi</span> <span class="pre">There!')</span></code> and <code class="docutils literal notranslate"><span class="pre">rotate(900,</span> <span class="pre">'z')</span></code>.</p></li> <li><p>All (short, long, unsigned) integer arguments or return values that are only used to specify the length of an array argument are omitted. For example, the C call</p> <div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">lmdef</span><span class="p">(</span><span class="n">deftype</span><span class="p">,</span> <span class="n">index</span><span class="p">,</span> <span class="n">np</span><span class="p">,</span> <span class="n">props</span><span class="p">)</span> </pre></div> </div> <p>is translated to Python as</p> <div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">lmdef</span><span class="p">(</span><span class="n">deftype</span><span class="p">,</span> <span class="n">index</span><span class="p">,</span> <span class="n">props</span><span class="p">)</span> </pre></div> </div> </li> <li><p>Output arguments are omitted from the argument list; they are transmitted as function return values instead. If more than one value must be returned, the return value is a tuple. If the C function has both a regular return value (that is not omitted because of the previous rule) and an output argument, the return value comes first in the tuple.
