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.
