Hi,

We need to test a function which reads a "record" from a binary file. We
want to compare the buffer with the "record" in input file.We know the
offset of the record in input file. How can we compare the
output_test_stream with a certain offset (and length) of the file? or is
there any alternative for this?

Thanks,
  Lloyd
