hi,
i want deal the data after FFT in my own block,i copy a
fft_lensizeof(gr_complex) length of data from in to a buffer,then deal
the data ,and copy the dealed data from buffer to the out,
in a FFT blocks,if there is
size_t block_size=output_signature()->sizeof_stream_item(0);
when i use memcpy(out,in,block_sizenoutput ); it works normally ,
but when i do it like this :memcpy(out,in, fft_len*sizeof(gr_complex)
);,it does not work
does the result of block_sizenoutput have any relations with
fft_lensizeof(gr_complex)
or some other suggestions
thanks,
BZS

Hi BZS,
you’re mixing concepts here: the FFT len is your FFT size, but noutput
is the number of items you are allowed to produce (maximum).
Please re-read the writing an out-of-tree module wiki page to
understand the difference better 
Greetings,
Marcus
