<function>glXGetProcAddress</function> returns the address of the function specified in <parameter>procName</parameter>. This is

necessary in environments where the OpenGL link library exports a different

set of functions than the runtime library.

<para>
|

A <constant>NULL</constant> pointer is returned if function requested is not suported
|
|
in the implementation being queried.

</para>

<para>
|
|
GLU functions are not queryable due to the fact that the library may not be
|

loaded at the time of the query.
