NAME
glGetPointerv
- return the address of the specified pointer
C SPECIFICATION
void glGetPointerv(
GLenum pname,
void **params )
delim $$
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.
