Function libeyelink_sys::setup_graphic_hook_functions_V2

pub unsafe extern "C" fn setup_graphic_hook_functions_V2(
    hooks: *mut HOOKFCNS2
) -> INT16

@ingroup display Primary function to setup display graphics hook functions of the second revision of the interface. One of the major difference between this and setup_graphic_hook_functions is, this has fewer functions to implement also, takes extra parameters like the major and minor versions for future enhancements.

\b Example:

@code
INT16 ELCALLTYPE init_expt_graphics(HWND hwnd, DISPLAYINFO *info)
{
HOOKFCNS2 fcns;
memset(&fcns,0,sizeof(fcns));
fcns.major = 1;
fcns.minor = 0;
fcns.userData = ts;

fcns.draw_image   = draw_image;
fcns.exit_image_display_hook= exit_image_display;
fcns.setup_image_display_hook = setup_image_display;



fcns.setup_cal_display_hook = setup_cal_display;
fcns.clear_cal_display_hook = clear_display;
fcns.erase_cal_target_hook  = clear_display;
fcns.draw_cal_target_hook   = draw_cal_target;
fcns.image_title_hook       = image_title;

fcns.get_input_key_hook     = get_input_key;
fcns.alert_printf_hook      = alert_printf_hook;
return setup_graphic_hook_functions_V2(&fcns);
}
