NAME

6       comedi_dio_config - change input/output properties of channel
7

SYNOPSIS

9       #include <comedilib.h>
10
11       int comedi_dio_config(comedi_t * device, unsigned int subdevice,
12                             unsigned int channel, unsigned int direction);
13

DESCRIPTION

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 direction. Valid directions are COMEDI_INPUT or COMEDI_OUTPUT.
18
19       Depending on the characteristics of the hardware device, multiple
20       channels might be grouped together in hardware when configuring the
21       input/output direction. In this case, a single call to
22       comedi_dio_config for any channel in the group will affect the entire
23       group.
24

RETURN VALUE

26       If successful, 0 is returned, otherwise -1.
