Re: [Discuss-gnuradio] Block with two or more outputs, with different sizes

[André Selva]

Josh,

The problem is that i don't know in advance the size of each stream. I'm kind of routing the input stream to the output streams, according to some information i read in each packet. So, I know a max value to the stream number of items, but cannot know certainly the output actual size. 

Att,

ok yes, see io_signaturev and some of the convenience factory functions
