Is there a "tail/skip/strip" block (counterpart of "head")

GNU Radio
#1

Before I go ahead and implement it myself
I was wondering if there is such a thing as a “tail”
or “skip” or “strip” block in gnuradio, that skips/ignores
the first K bytes and passes to the output the rest.

Thanks

Hi Achilleas,

There’s gr.skiphead(sizeof_item, nitems_to_skip)

/*!

  • \brief skips the first N items, from then on copies items to the
    output
  • \ingroup block
  • Useful for building test cases and sources which have metadata or
    junk at the start
    */

class gr_skiphead : public gr_sync_block
{
friend gr_block_sptr gr_make_skiphead (size_t sizeof_stream_item, int
nitems);
gr_skiphead (size_t sizeof_stream_item, int nitems);
