I'm attempting to bring Musubi by Mark Akita, up to date to use the sdl2 library, and I've run into an odd problem. Apparently there are too many parameters in the call_func/proc

This is the error 

D:\EuProgramming\Phix\SDL2\Musubi\EuSDL2.ew:1490 in function SDL_SaveBMP() 
too many parameters in call_func/proc() 
    surf = 48975048 
    fname = `Demo_01.bmp` 
    sptr = 7289584 
    rwops = 48975256 
... called from D:\EuProgramming\Phix\SDL2\Musubi\Musubi2.ew:691 in function M_save_screen() 
    o1 = 1 
    fname = `Demo_01.bmp` 
    surf = 48975048 
... called from D:\EuProgramming\Phix\SDL2\Musubi\Musubi_Demo_01.exw:67

these are the relevant code snippets 

xSDL_SaveBMP_RW = define_c_func(sdl2,"+SDL_SaveBMP_RW",{C_POINTER,C_POINTER,C_INT},C_INT), 
 
public function SDL_SaveBMP(atom surf, sequence fname) 
atom sptr = allocate_string(fname ) 
atom rwops = SDL_RWFromFile(fname,"wb") 
 
    return xSDL_SaveBMP_RW(surf, rwops, 1)   --<--line 1490 
  
    --return xSDL_SaveBMP(surf, fname)      --will never work, routine id is -1 
end function 
 

test=M_save_screen(1,"Demo_01.bmp") 
 
----------------------------------------------------------------------- 
global function M_save_screen(object o1, sequence fname) 
----------------------------------------------------------------------- 
atom surf 
 
surf = SDL_GetWindowSurface(sdlWindow) 
VOID = SDL_SaveBMP(surf, fname) 
 
return VOID 
end function

Any ideas gratefully received.

Cheers

Chris
