U2C_RESULT U2C_SingleIoWrite (
            HANDLE hDevice,
             ULONG IoNumber,
             BOOL Value
);

The U2C_SingleIoWrite function sets the output value of the specified GPIO pin. Pin must be configured as output using U2C_SetIoDirection() or U2C_SetSingleIoDirection() functions first.

Parameters:

	hDevice	Handle to the U2C-12 device.
	IoNumber	The number of the GPIO pin to set output value to: Numbers 0..7 correspond to Port A pins 0..7 Numbers 8..15 correspond to Port B pins 0..7 Number 16..23 correspond to Port C pins 0..7
	Value	The GPIO pin new output value.

Return values:

	U2C_SUCCESS	The GPIO pin output value was successfully modified.
	U2C_HARDWARE_NOT_FOUND	U2C-12 device referenced by hDevice handle was not found.
	U2C_BAD_PARAMETER	IoNumber is out of range.
