GLGETPOINTERV(3G) GLGETPOINTERV(3G)
NAME
glGetPointerv - return the address of the specified pointer
C SPECIFICATION
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
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.
