DESCRIPTION

14       The  function  comedi_do_insn()  performs  a  single  instruction.   If
15       sucessful, comedi_do_insn() returns the  number  of  samples  measured,
16       which  may be less than the number of requested samples.  Comedi limits
17       the number of requested samples in order to enforce fairness among pro‐
18       cesses.  If there is an error, -1 is returned.
