gluGetString  - return a string describing the GLU version
       or GLU extensions



C SPECIFICATION

       const GLubyte * gluGetString( GLenum name )



PARAMETERS

       name  Specifies a symbolic constant, one  of  GLU_VERSION,
             or GLU_EXTENSIONS.


DESCRIPTION

       gluGetString returns a pointer to a static string describ-
       ing the GLU version or the GLU extensions  that  are  sup-
       ported.

       The version number is one of the following forms:

       major_number.minor_number
       major_number.minor_number.release_number.

       The version string is of the following form:

       version number<space>vendor-specific information

       Vendor-specific  information  is optional.  Its format and
       contents depend on the implementation.

       The standard GLU contains a  basic  set  of  features  and
       capabilities.   If a company or group of companies wish to
       support other features, these may be  included  as  exten-
       sions  to  the  GLU.   If  name  is  GLU_EXTENSIONS,  then
       gluGetString returns a space-separated list  of  names  of
       supported  GLU extensions.  (Extension names never contain
       spaces.)

       All strings are null-terminated.


NOTES

       gluGetString only returns  information  about  GLU  exten-
       sions. Call glGetString to get a list of GL extensions.

       gluGetString  is  an  initialization  routine.  Calling it
       after a glNewList results in undefined behavior.


ERRORS

       NULL  is  returned  if  name   is   not   GLU_VERSION   or
       GLU_EXTENSIONS.
