glXGetClientString()                         glXGetClientString()

NAME    [Toc]    [Back]

       glXGetClientString - return a string describing the client

SYNOPSIS    [Toc]    [Back]

       const char * glXGetClientString(
               Display *dpy,
               int name );

PARAMETERS    [Toc]    [Back]

       Specifies the connection to the X server.  Specifies which
       string  is  returned.  One  of GLX_VENDOR, GLX_VERSION, or
       GLX_EXTENSIONS.

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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
       extensions  supported by the client. Call glGetString() to
       get a list of GL extensions supported by the server.
