Yes, for Windows. In a .so file for Linux.

No. You open the DLL first, then get the id of the function inside the DLL.
To quote from the Euphoria manual...
user32 = open_dll("user32.dll")
-- the C function BeginPaint takes a C int argument and
-- a C pointer, and returns a C int as a result:
BeginPaint = define_c_func(user32, "BeginPaint",
{C_INT, C_POINTER}, C_INT)
-- call BeginPaint, passing hwnd and ps as the arguments,
-- hdc is assigned the result:
hdc = c_func(BeginPaint, {hwnd, ps})
--
cheers,
