6 | <code class="function">glXGetProcAddress</code> returns the address of the function specified in <em class="parameter"><code>procName</code></em>. This is | |
7 | necessary in environments where the OpenGL link library exports a different | |
8 | set of functions than the runtime library. | |

10 | A <code class="constant">NULL</code> pointer is returned if function requested is not suported | |
11 | in the implementation being queried. | |
12 | </p><p> | |
13 | GLU functions are not queryable due to the fact that the library may not be | |
14 | loaded at the time of the query. | |
