12 unsigned int channel, unsigned int direction);

15 The function comedi_dio_config() configures individual channels in a
16 digital I/O subdevice to be either input or output, depending on the
17 value of parameter direction. Valid directions are COMEDI_INPUT or
18 COMEDI_OUTPUT.
19
20 Depending on the capabilities of the hardware device, multiple channels
21 may be grouped together to determine direction. In this case, a single
22 call to comedi_dio_config() for any channel in the group will affect
23 the entire group.

25 If sucessful, 1 is returned, otherwise -1.
