	  error	code


     FORTRAN SPECIFICATION
	  CHARACTER*256	 fgluErrorString( INTEGER*4 error )


     PARAMETERS
	  error	 Specifies a GL	or GLU error code.

     DESCRIPTION
	  fgluErrorString produces an error string from	a GL or	GLU
	  error	code. The string is in ISO Latin 1 format. For
	  example, fgluErrorString(GL_OUT_OF_MEMORY) returns the
	  string out of	memory.

	  The standard GLU error codes are GLU_INVALID_ENUM,
	  GLU_INVALID_VALUE, and GLU_OUT_OF_MEMORY.  Certain other GLU
	  functions can	return specialized error codes through
	  callbacks.  See the glGetError reference page	for the	list
	  of GL	error codes.
