Thank you Eric,
But I still have a problem. I simply made two blocks.
1) First One
gr_data_parser::gr_data_parser ()
: gr_block ("gr_data_parser",
gr_make_io_signature (1, 1, sizeof (gr_complex)),
gr_make_io_signature (1, 2, sizeof (gr_complex)))
2) Second One
gr_data_parser2::gr_data_parser2 ()
: gr_block ("gr_data_parser2",
gr_make_io_signature (1, 2, sizeof (gr_complex)),
gr_make_io_signature (1, 1, sizeof (gr_complex)))
And I connect above two blocks in following way.
self.connect(self.u, ..... , data_parser, data_parser2 , .... self. u);
I put a debug code in the function 'general_work()' of first function, I
just can have
output_items.size() = 1
The number of output stream of first block could not be changed. Is there
any other point I should change?
Thanks in advance
Yong
