gluGetString(3G)

NAME
     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 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
     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.
