GLGETPOINTERV(3G)						   OpenGL Manual						 GLGETPOINTERV(3G)

NAME

       glGetPointerv - return the address of the specified pointer

C SPECIFICATION

       void glGetPointerv(GLenum pname, GLvoid ** params);

PARAMETERS

       pname
	   Specifies the array or buffer pointer to be returned. Symbolic constants GL_COLOR_ARRAY_POINTER, GL_EDGE_FLAG_ARRAY_POINTER,
	   GL_FOG_COORD_ARRAY_POINTER, GL_FEEDBACK_BUFFER_POINTER, GL_INDEX_ARRAY_POINTER, GL_NORMAL_ARRAY_POINTER,
	   GL_SECONDARY_COLOR_ARRAY_POINTER, GL_SELECTION_BUFFER_POINTER, GL_TEXTURE_COORD_ARRAY_POINTER, or GL_VERTEX_ARRAY_POINTER are accepted.

       params
	   Returns the pointer value specified by pname.

DESCRIPTION

       glGetPointerv returns pointer information.  pname is a symbolic constant indicating the pointer to be returned, and params is a pointer to
       a location in which to place the returned data.

       For all pname arguments except GL_FEEDBACK_BUFFER_POINTER and GL_SELECTION_BUFFER_POINTER, if a non-zero named buffer object was bound to
       the GL_ARRAY_BUFFER target (see glBindBuffer()) when the desired pointer was previously specified, the pointer returned is a byte offset
       into the buffer object's data store. Buffer objects are only available in OpenGL versions 1.5 and greater.

NOTES

       glGetPointerv is available only if the GL version is 1.1 or greater.

       GL_FOG_COORD_ARRAY_POINTER and GL_SECONDARY_COLOR_ARRAY_POINTER are available only if the GL version is 1.4 or greater.

       The pointers are all client-side state.

       The initial value for each pointer is 0.

       For OpenGL versions 1.3 and greater, or when the ARB_multitexture extension is supported, querying the GL_TEXTURE_COORD_ARRAY_POINTER
       returns the value for the active client texture unit.

ERRORS

       GL_INVALID_ENUM is generated if pname is not an accepted value.

GLGETMINMAXPARAMETER(3G)					   OpenGL Manual					  GLGETMINMAXPARAMETER(3G)

NAME

       glGetMinmaxParameter - get minmax parameters

C SPECIFICATION

       void glGetMinmaxParameterfv(GLenum target, GLenum pname, GLfloat * params);

       void glGetMinmaxParameteriv(GLenum target, GLenum pname, GLint * params);

PARAMETERS

       target
	   Must be GL_MINMAX.

       pname
	   The parameter to be retrieved. Must be one of GL_MINMAX_FORMAT or GL_MINMAX_SINK.

       params
	   A pointer to storage for the retrieved parameters.

DESCRIPTION

       glGetMinmaxParameter retrieves parameters for the current minmax table by setting pname to one of the following values:

       +----------------------------------+-------------------------------------+
       |				  |					|
       |			Parameter |			    Description |
       |				  |					|
       +----------------------------------+-------------------------------------+
       |GL_MINMAX_FORMAT		  | Internal format of minmax table	|
       +----------------------------------+-------------------------------------+
       |GL_MINMAX_SINK			  | Value of the sink parameter 	|
       +----------------------------------+-------------------------------------+

NOTES

       glGetMinmaxParameter is present only if ARB_imaging is returned when glGetString() is called with an argument of GL_EXTENSIONS.

ERRORS

       GL_INVALID_ENUM is generated if target is not GL_MINMAX.

       GL_INVALID_ENUM is generated if pname is not one of the allowable values.

       GL_INVALID_OPERATION is generated if glGetMinmaxParameter is executed between the execution of glBegin() and the corresponding execution of
       glEnd().
