glGetPointerv( GLenum pname,
void **params )
eqn not supported
- 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.
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.
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.
GL_INVALID_ENUM is generated if
pname is not an accepted value.
