Looks like there isn't one. XGetIconSizes() returns a list
of "XIconSize" structs. I couldn't figure out how to return
a list, so i'm just using the first one:


//xcb_wm_hints_t
/**
  * @brief Size hints structure.
  */
typedef struct {
   /** WM-specified minimum icon size */
   uint32_t min_width, min_height;
   /** WM-specified maximum icon size */
   uint32_t max_width, max_height;
   /** WM-specified resize increments */
   int32_t width_inc, height_inc;
} xcb_wm_icon_size_hints_hints_t;

/** Number of elements in this structure */
#define XCB_NUM_WM_ICON_SIZE_HINTS_ELEMENTS 6

//xcb_get_wm_hints
xcb_get_property_cookie_t
xcb_get_wm_icon_size_hints(xcb_connection_t *c, xcb_window_t window)
{
   return xcb_get_property(c, 0, window, WM_ICON_SIZE, WM_ICON_SIZE, 0L, 
XCB_NUM_WM_ICON_SIZE_HINTS_ELEMENTS);	// 60L in Xlib
}

//xcb_get_wm_hints_unchecked
xcb_get_property_cookie_t
xcb_get_wm_icon_size_hints_unchecked(xcb_connection_t *c, xcb_window_t window)
{
   return xcb_get_property_unchecked(c, 0, window, WM_ICON_SIZE, WM_ICON_SIZE, 
0L, XCB_NUM_WM_ICON_SIZE_HINTS_ELEMENTS);	// 60L in Xlib
}

//xcb_get_wm_hints_from_reply
uint8_t
xcb_get_wm_icon_size_hints_from_reply(xcb_wm_icon_size_hints_hints_t *hints,
                             xcb_get_property_reply_t *reply)
{
   if(!reply)
     return 0;

   int length = xcb_get_property_value_length(reply);

   if ((reply->type != WM_ICON_SIZE) ||
       (length < (XCB_NUM_WM_ICON_SIZE_HINTS_ELEMENTS - 1)) ||
       (reply->format != 32))
     return 0;

   memcpy(hints, (xcb_wm_icon_size_hints_hints_t *) xcb_get_property_value(reply),
          length * reply->format >> 3);

   return 1;
}

//xcb_get_wm_hints_reply
uint8_t
xcb_get_wm_icon_size_hints_reply(xcb_connection_t *c,
                        xcb_get_property_cookie_t cookie,
                        xcb_wm_icon_size_hints_hints_t *hints,
                        xcb_generic_error_t **e)
{
   xcb_get_property_reply_t *reply = xcb_get_property_reply(c, cookie, e);
   int ret = xcb_get_wm_icon_size_hints_from_reply(hints, reply);
   free(reply);
   return ret;
}
