GLGETTEXPARAMETER()					   GLGETTEXPARAMETER()

NAME
       glGetTexParameterfv,  glGetTexParameteriv  -  return  texture parameter
       values

C SPECIFICATION
       void glGetTexParameterfv( GLenum	target,
				 GLenum	pname,
				 GLfloat *params )
       void glGetTexParameteriv( GLenum	target,
				 GLenum	pname,
				 GLint *params )

       delim $$

PARAMETERS
       target  Specifies the symbolic name of  the  target  texture.   GL_TEX-
	       TURE_1D and GL_TEXTURE_2D are accepted.

       pname   Specifies  the  symbolic	 name of a texture parameter.  GL_TEX-
	       TURE_MAG_FILTER,	  GL_TEXTURE_MIN_FILTER,    GL_TEXTURE_WRAP_S,
	       GL_TEXTURE_WRAP_T,  GL_TEXTURE_BORDER_COLOR,  GL_TEXTURE_PRIOR-
	       ITY, and	GL_TEXTURE_RESIDENT are	accepted.

       params  Returns the texture parameters.

DESCRIPTION
       glGetTexParameter returns in params the value or	values of the  texture
       parameter  specified  as	pname.	target defines the target texture, ei-
       ther GL_TEXTURE_1D or GL_TEXTURE_2D, to specify one- or two-dimensional
       texturing.  pname accepts the same symbols as glTexParameter, with  the
       same interpretations:

       GL_TEXTURE_MAG_FILTER		  Returns  the	single-valued  texture
					  magnification	 filter,  a   symbolic
					  constant.   The   initial  value  is
					  GL_LINEAR.

       GL_TEXTURE_MIN_FILTER		  Returns  the	single-valued  texture
					  minification filter, a symbolic con-
					  stant. The initial value is GL_NEAR-
					  EST_MIPMAP_LINEAR.

       GL_TEXTURE_WRAP_S		  Returns  the	single-valued wrapping
					  function for texture coordinate $s$,
					  a  symbolic  constant.  The  initial
					  value	is GL_REPEAT.

       GL_TEXTURE_WRAP_T		  Returns  the	single-valued wrapping
					  function for texture coordinate $t$,
					  a  symbolic  constant.  The  initial
					  value	is GL_REPEAT.

       GL_TEXTURE_BORDER_COLOR		  Returns  four	 integer  or floating-
					  point	numbers	that comprise the RGBA
					  color	of the texture border.	Float-
					  ing-point values are returned	in the
					  range	[0, 1].	  Integer  values  are
					  returned  as a linear	mapping	of the
					  internal floating-point  representa-
					  tion	such that 1.0 maps to the most
					  positive representable  integer  and
					  -1.0	maps to	the most negative rep-
					  resentable  integer.	 The   initial
					  value	is (0, 0, 0, 0).

       GL_TEXTURE_PRIORITY		  Returns  the	residence  priority of
					  the target  texture  (or  the	 named
					  texture  bound  to  it). The initial
					  value	is  1.	 See  glPrioritizeTex-
					  tures.

       GL_TEXTURE_RESIDENT		  Returns  the residence status	of the
					  target texture.  If  the  value  re-
					  turned  in  params  is  GL_TRUE, the
					  texture is resident in texture  mem-
					  ory.	See glAreTexturesResident.

NOTES
       GL_TEXTURE_PRIORITY  and	 GL_TEXTURE_RESIDENT are only available	if the
       GL version is 1.1 or greater.

       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 glGetTexParameter is executed be-
       tween the execution of  glBegin	and  the  corresponding	 execution  of
       glEnd.
