GLGETPOINTERV(3G)   UNIX Programmer's Manual    GLGETPOINTERV(3G)

NAME

     glGetPointerv - return the address of the specified pointer

C SPECIFICATION

     void glGetPointerv( GLenum pname,
                         void **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 sym-
     bolic 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, query-
     ing 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.
