[Discuss-gnuradio] File seek - 1st attempt

[cswiger]

Since it's my itch to scratch, I made a (w)hack at it and
got promising results. Using as an example gr_freq_xlating_fir_filter
method set_center_freq, we add to

gr_file_source.cc:

void
gr_file_source::seek(long seek_point)
{
    fseek ((FILE *) d_fp, seek_point, SEEK_SET);
}


and to gr_file_source.h

 public:
  void seek(long seek_point);


finally to gr_file_source.i

 public
  void seek (long seek_point);



recompile and it seems to work with initial testing comprised of
'press a key and seek to 100000' which always plays the same
material as expected. Cool.
