mfb_update(window, buffer)

Update the display. Input buffer is assumed to be a 32-bit buffer of the size given in the open call. Will return a negative status if something went wrong or the user want to exit. Also updates the window event

mfb_set_user_data(window , user_data::Ptr{Cvoid})

Set a per-window user data. Data is supplied as a pointer. The data at the end of that pointer should be prevented from garbage collection.

Example

x=Ref(2)
mfb_set_user_data(w, x)

See also: mfb_get_user_data

mfb_get_user_data(window)::Ptr{Cvoid}

Retrive the user data associated with this window. The return value is a void pointer that should be derferenced

Example

g=mfb_get_user_data(w)
unsafe_load(convert(Ptr{Int}, g)) # 2
