const GLubyte * GLAPIENTRY 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 describing the GLU
       version or the GLU extensions that are supported.

       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 extensions 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 extensions. Call glGet‐
       String 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.
