><P
>The function comedi_do_insn() performs a single instruction.
If sucessful, comedi_do_insn() returns the number of samples
measured, which may be less than the number of requested
samples. Comedi limits the number of requested samples in
order to enforce fairness among processes. If there is an
error, -1 is returned.</P
