> Description
</H2
><P
>The function comedi_dio_config() configures individual channels
in a digital I/O subdevice to be either input or output, depending
on the value of parameter direction. Valid directions are
COMEDI_INPUT or COMEDI_OUTPUT.</P
><P
>Depending on the capabilities of the hardware device, multiple
channels may be grouped together to determine direction. In this
case, a single call to comedi_dio_config() for any channel in the
group will affect the entire group.</P
><P
>If sucessful, 1 is returned, otherwise -1.</P
