- int comedi_dio_write(comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int bit);
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.
If you wish to write multiple digital channels at once, it is more efficient to use comedi_dio_bitfield2 than to call this function multiple times.
Return values and errors are the same as comedi_data_write.
