"CVI short data type in DIG_Out_Grp function.

In using the DIG_Out_Grp function, the data type specified is short, but the examples show an i32 (long)being used. If a GROUP can be made up of 2-4 ports, how can this function be asking for a data type of short? Or is there a definition error or typo? What am I missing?

Even though an i32 is being used, only the least significant 2 bytes are written. For sending more than 2 bytes DIG_Block_Out must be used.
