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 implementation 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 contents 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.  If the GLX version
       is 1.3, then the GL version must be 1.2.

       glXGetClientString  only  returns  information about GLX extensions sup‐
       ported by the client.  Call glGetString to get a list of  GL  extensions
       supported by the server.
