Hi all,
I'm not sure about how to read and write PMT ports from and to local variables. I'm going to expose what i'm doing, and if someone can help me i would be very greatful.
I've created an input and an output of PMT type.
message_port_register_in(pmt::pmt_t in_threshold)
message_port_register_out(pmt::pmt_t out_threshold)
Now i want to read the port, and save the data in a local variable, do operations with that variable, and later write it in the output,
I create the variables,
double d_threshold;
pmt::pmt_t target;
I read it, I don't know how to do it. But I suppose:
And, I think i can write it as follows:
What do you think, i've seen several examples, and they do this, message_port_pub(pmt::mp("symbols"), pmt::cons(pmt::make_dict(), pmt::init_c32vector(48, symbols)));
But I don't understand why it is necessary to use pmt::make_dict().
Thanks in advance.
Best regards,
Cristian
