comedi_dio_config - change input/output properties of channel
#include <comedilib.h> int comedi_dio_config(comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int direction);
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 direction. Valid directions are COMEDI_INPUT or COMEDI_OUTPUT. Depending on the characteristics of the hardware device, multiple channels might be grouped together in hardware when configuring the input/output direction. In this case, a single call to comedi_dio_config for any channel in the group will affect the entire group.
If successful, 0 is returned, otherwise -1.
