Example
Calling the function in ST and decoding of the return value:
(* open CAN driver - returns g_dwReturnValue *)
g_dwReturnValue:= L_CanInit(10, 0);
g_bInitOK := NOT DWORD_TO_BOOL(g_dwReturnValue AND 16#0000_0001);
g_bDriverFail := DWORD_TO_BOOL(SHR(g_dwReturnValue,1) AND 16#0000_0001);
g_wVersion := DWORD_TO_WORD(SHR(g_dwReturnValue,16) AND 16#FFFF);
