- return the address of the specified pointer
C SPECIFICATION
PARAMETERS
_param1 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.
_param2 Returns the pointer value specified by _param1.
DESCRIPTION
glGetPointerv returns pointer information. _param1 is a
symbolic constant indicating the pointer to be returned,
and _param2 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 _param1 is not an accepted
value.
