<para>
<function>glXCreatePixmap</function> creates an off-screen rendering area and returns its XID.
Any GLX rendering context that was created with respect to <parameter>config</parameter>
can be used to render into this window.
Use <citerefentry><refentrytitle>glXMakeCurrent</refentrytitle></citerefentry> to associate the rendering area with a GLX
rendering context.

<refsect1 id="notes"><title>Notes</title>
<para>
<function>glXCreatePixmap</function> is available only if the GLX version is 1.3 or greater.
</para>
<para>
If the GLX version is 1.1 or 1.0, the GL version must be 1.0.
If the GLX version is 1.2, then the GL version must be 1.1.
If the GLX version is 1.3, then the GL version must be 1.2.

<para>
<constant>BadMatch</constant> is generated if <parameter>pixmap</parameter> was not created with a visual
that corresponds to <parameter>config</parameter>.
</para>
<para>
<constant>BadMatch</constant> is generated if <parameter>config</parameter> does not support rendering to
windows (e.g., <constant>GLX_DRAWABLE_TYPE</constant> does not contain
<constant>GLX_WINDOW_BIT</constant>).
</para>
<para>
<constant>BadWindow</constant> is generated if <parameter>pixmap</parameter> is not a valid window XID.
<constant>BadAlloc</constant> is generated if there is already a GLXFBConfig
associated with <parameter>pixmap</parameter>.
</para>
<para>
<constant>BadAlloc</constant> is generated if the X server cannot allocate a new
GLX window.
</para>
<para>
<constant>GLXBadFBConfig</constant> is generated if <parameter>config</parameter> is not a valid
GLXFBConfig.
