## Description

`glXQueryServerString` returns a pointer to a static, null-terminated string describing some aspect of the server's GLX extension. The possible values for name and the format of the strings is the same as for glXGetClientString. If name is not set to a recognized value, `NULL` is returned.

## Notes

`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. If the GLX version is 1.3, the GL version must be 1.2.

`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.
