[Discuss-gnuradio] help on gr_make_io_signature

[ramanagouda odugoudar]

Hi,
   I am writing a block to concatenated data from two input streams of different length and i am using following I/O signatures

ACS_combine_vff::ACS_combine_vff(int len)
  : gr_sync_block("ACS_combine_vff",
          gr_make_io_signature(1,2, sizeof(float)*len),
          gr_make_io_signature(1,1, sizeof(float)*2*len))
    
{
    d_len=len;

}

suppose if i have first input stream of length 10 and second input stream of length 5 , how should i modify the above I/O signature to make sure output stream has length 15 .

thanks in advance
Raman
