Ok, I suppose the best and fastest way to learn gnuradio is by exploring
simple existing blocks, like adder for example.
I was first thinking about adder and the opened gr_add_cc.h.
I was immediately stuck in the constructor part
gr_add_cc::gr_add_cc (size_t vlen)
: gr_sync_block ("add_cc",
gr_make_io_signature (1, -1, sizeof (gr_complex)*vlen),
gr_make_io_signature (1, 1, sizeof (gr_complex)*vlen)),
d_vlen (vlen)
{
}
I was expecting something like:
gr_add_cc::gr_add_cc (size_t vlen)
: gr_sync_block ("add_cc",
gr_make_io_signature (1, vlen, sizeof (gr_complex)),
gr_make_io_signature (1, 1, sizeof (gr_complex))),
d_vlen (vlen)
{
}
I don't really understand this line:
gr_make_io_signature (1, -1, sizeof (gr_complex)*vlen)
Can you just explain breafly what is idea behind, cause i was expecting
something more simpler.
Thanks
