DESCRIPTION
       glXQueryExtensionsString  returns a pointer to a string describing which
       GLX extensions are supported on the connection. The string is  null-ter‐
       minated  and  contains  a space-separated list of extension names.  (The
       extension names themselves never contain spaces.) If there are no exten‐
       sions to GLX, then the empty string is returned.

NOTES
       glXQueryExtensionsString  is available only if the GLX version is 1.1 or
       greater.

       glXQueryExtensionsString only returns information about GLX  extensions.
       Call glGetString to get a list of GL extensions.
