Start and Stop Processing

Start processing and stop processing are common processing required in all programming.

Start processing is performed using the StartOperation function.
This function starts signal output from the specified device.

Stop processing is performed using the StopOperation function.
This function stops signal output from the specified device.

Both the StartOperation and StopOperation functions have one parameter.
The first parameter specifies "0".

If both the StartOperation and StopOperation functions complete normally, the return value (Ret) is 0.
If the function fails to execute, a value other than 0 is returned.
