comedi_dio_write - write single bit to digital channel
int comedi_dio_write (comedi_t * device, unsigned int subdevice,
unsigned int channel, unsigned int bit);
The function writes the value bit to the channel channel belonging to
the subdevice subdevice of device device. This function is equivalent
to comedi_data_write(device,subdevice,channel,0,0,bit). This function
does not require a digital subdevice or a subdevice with a maximum data
value of 1 to work properly.
Return values and errors are the same as comedi_data_write().
