GLGETPOINTERV(3G)														 GLGETPOINTERV(3G)

NAME

       glGetPointerv - return the address of the specified pointer

C SPECIFICATION

       void glGetPointerv( GLenum pname,
			   void **params )

PARAMETERS

       pname   Specifies  the  array  or  buffer  pointer  to be returned.  Symbolic constants GL_COLOR_ARRAY_POINTER, GL_EDGE_FLAG_ARRAY_POINTER,
	       GL_FEEDBACK_BUFFER_POINTER,	  GL_INDEX_ARRAY_POINTER,	  GL_NORMAL_ARRAY_POINTER,	   GL_TEXTURE_COORD_ARRAY_POINTER,
	       GL_SELECTION_BUFFER_POINTER, and 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.

NOTES

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

       The pointers are all client-side state.

       The initial value for each pointer is 0.

       When the GL_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.

GLENABLECLIENTSTATE(3G) 												   GLENABLECLIENTSTATE(3G)

NAME

       glEnableClientState, glDisableClientState - enable or disable client-side capability

C SPECIFICATION

       void glEnableClientState( GLenum cap);  1.1 )

PARAMETERS

       1.1  Specifies  the  capability	to  enable.   Symbolic	constants  GL_COLOR_ARRAY,  GL_EDGE_FLAG_ARRAY,  GL_INDEX_ARRAY,  GL_NORMAL_ARRAY,
	    GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY are accepted.

C SPECIFICATION

       void glDisableClientState( GLenum cap);	1.1 )

PARAMETERS

       1.1    Specifies the capability to disable.

DESCRIPTION

       glEnableClientState and glDisableClientState enable or disable individual client-side capabilities. By default, all  client-side  capabili-
       ties  are  disabled.   Both glEnableClientState and glDisableClientState take a single argument, 1.1, which can assume one of the following
       values:

       GL_COLOR_ARRAY		If enabled, the color array is enabled for writing and used during rendering  when  glArrayElement,  glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glColorPointer.

       GL_EDGE_FLAG_ARRAY	If  enabled,  the  edge  flag  array  is  enabled  for	writing  and  used  during  rendering when glArrayElement,
				glDrawArrays, glDrawElement, or glDrawRangeElements is called. See glEdgeFlagPointer.

       GL_INDEX_ARRAY		If enabled, the index array is enabled for writing and used during rendering  when  glArrayElement,  glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glIndexPointer.

       GL_NORMAL_ARRAY		If  enabled,  the normal array is enabled for writing and used during rendering when glArrayElement, glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glNormalPointer.

       GL_TEXTURE_COORD_ARRAY	If enabled, the texture coordinate array is enabled for writing and used  during  rendering  when  glArrayElement,
				glDrawArrays, glDrawElement, or glDrawRangeElements is called. See glTexCoordPointer.

       GL_VERTEX_ARRAY		If  enabled,  the vertex array is enabled for writing and used during rendering when glArrayElement, glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glVertexPointer.

NOTES

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

       If GL_ARB_multitexture is supported, enabling and disabling GL_TEXTURE_COORD_ARRAY affects the active  client  texture  unit.   The  active
       client texture unit is controlled with glClientActiveTextureARB.

ERRORS

       GL_INVALID_ENUM is generated if 1.1 is not an accepted value.

       glEnableClientState  is not allowed between the execution of glBegin and the corresponding glEnd, but an error may or may not be generated.
       If no error is generated, the behavior is undefined.
