of the strings is the same as for glXGetClientString. If name is not set to a recognized

value, NULL is returned.

glXQueryServerString is available only if the GLX version is 1.1 or greater.

If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, the

GL version must be 1.1.

glXQueryServerString only returns information about GLX extensions supported by the

server. Call glGetString to get a list of GL extensions. Call glXGetClientString to get a

list of GLX extensions supported by the client.
