SYNOPSIS

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

DESCRIPTION

15       The function reads the channel channel belonging to the subdevice  sub‐
16       device  of device device.  The data value that is read is stored in the
17       location  pointed  to  by  bit.   This  function   is   equivalent   to
18       comedi_data_read(device,subdevice,channel,0,0,bit).  This function does
19       not require a digital subdevice or a  subdevice  with  a  maximum  data
20       value of 1 to work properly.
