NAME
     glXGetClientString - return a string describing the client


C SPECIFICATION
     const char * glXGetClientString( Display *dpy,
                                      int name )


PARAMETERS
     dpy   Specifies the connection to the X server.

     name  Specifies  which   string   is   returned.    One   of
           GLX_VENDOR, GLX_VERSION, or GLX_EXTENSIONS.

DESCRIPTION
     glXGetClientString returns a string describing  some  aspect
     of  the  client  library.  The  possible values for name are
     GLX_VENDOR, GLX_VERSION, and GLX_EXTENSIONS. If name is  not
     set to one of these values, glXGetClientString returns NULL.
     The format and contents of the vendor string is  implementa-
     tion dependent.

     The extensions string  is  null-terminated  and  contains  a
     space-separated  list  of   extension  names. (The extension
     names never contain spaces.) If there are no  extensions  to
     GLX, then the empty string is returned.

     The version string is laid out as follows:

     <major_version.minor_version><space><vendor-specific info>

     Both the major and minor portions of the version number  are
     of  arbitrary  length.   The  vendor-specific information is
     optional.  However, if it is present, the  format  and  con-
     tents are implementation specific.

NOTES
     glXGetClientString 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, then the GL version must be
     1.1.

     glXGetClientString only returns information about GLX exten-
     sions  supported  by  the  client. Call glGetString to get a
     list of GL extensions supported by the server.
