Purpose

Returns the address of the specified pointer.

Library

OpenGL C bindings library: libGL.a

C Syntax

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_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

The glGetPointerv subroutine returns pointer information. The pname parameter 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.
