>The function reads the channel channel belonging to the
subdevice subdevice of device device. The data value that is
read is stored in the location pointed to by bit. This function
is equivalent to comedi_data_read(device,subdevice,channel,0,0,bit).
This function does not require a digital subdevice or a subdevice
with a maximum data value of 1 to work properly.</P

>Return values and errors are the same as comedi_data_read().</P
