NAME

comedi_dio_config - change input/output properties of channel  

SYNOPSIS

#include <comedilib.h>

int comedi_dio_config (comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int direction);  

DESCRIPTION

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.

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.

If sucessful, 1 is returned, otherwise -1.
