14 | <code class="function">glXCreatePixmap</code> creates an off-screen rendering area and returns its XID. | |
15 | Any GLX rendering context that was created with respect to <em class="parameter"><code>config</code></em> | |
16 | can be used to render into this window. | |
17 | Use <a class="citerefentry" href="glXMakeCurrent.xml"><span class="citerefentry"><span class="refentrytitle">glXMakeCurrent</span></span></a> to associate the rendering area with a GLX | |
18 | rendering context. | |

20 | <code class="function">glXCreatePixmap</code> is available only if the GLX version is 1.3 or greater. | |
21 | </p><p> | |
22 | If the GLX version is 1.1 or 1.0, the GL version must be 1.0. | |
23 | If the GLX version is 1.2, then the GL version must be 1.1. | |

36 | </p><p> | |
37 | <code class="constant">BadAlloc</code> is generated if the X server cannot allocate a new | |
