NAME
	  fglGetTexEnvfv, fglGetTexEnviv - return texture environment
	  parameters


     FORTRAN SPECIFICATION
	  SUBROUTINE fglGetTexEnvfv( INTEGER*4 target,
				     INTEGER*4 pname,
				     CHARACTER*8 params	)
	  SUBROUTINE fglGetTexEnviv( INTEGER*4 target,
				     INTEGER*4 pname,
				     CHARACTER*8 params	)


     PARAMETERS
	  target  Specifies a texture environment.  Must be
		  GL_TEXTURE_ENV.

	  pname	  Specifies the	symbolic name of a texture environment
		  parameter.  Accepted values are GL_TEXTURE_ENV_MODE
		  and GL_TEXTURE_ENV_COLOR.

	  params  Returns the requested	data.

     DESCRIPTION
	  fglGetTexEnv returns in params selected values of a texture
	  environment that was specified with fglTexEnv.  target
	  specifies a texture environment.  Currently, only one
	  texture environment is defined and supported:
	  GL_TEXTURE_ENV.

	  pname	names a	specific texture environment parameter,	as
	  follows:

	  GL_TEXTURE_ENV_MODE
		    params returns the single-valued texture
		    environment	mode, a	symbolic constant. The initial
		    value is GL_MODULATE.

	  GL_TEXTURE_ENV_COLOR
		    params returns four	integer	or floating-point
		    values that	are the	texture	environment color.
		    Integer values, when requested, are	linearly
		    mapped from	the internal floating-point
		    representation such	that 1.0 maps to the most
		    positive representable integer, and	-1.0 maps to
		    the	most negative representable integer. The
		    initial value is (0, 0, 0, 0).

     NOTES
	  If an	error is generated, no change is made to the contents
	  of params.
     ERRORS
	  GL_INVALID_ENUM is generated if target or pname is not an
	  accepted value.

	  GL_INVALID_OPERATION is generated if fglGetTexEnv is
	  executed between the execution of fglBegin and the
	  corresponding	execution of fglEnd.
