Re: [Discuss-gnuradio] Accessing the uhd_usrp object

[Marcus Müller]

Hi Ranga,

that's what pointers are for, after all. Just do it! Thanks to the make()-magic you basically always have a smart shared pointer instead of an block object (unless you really try to break the system ;) ).

Just a quick note though: MAC is usually timing-relevant. Timed commands might not work as you expect, so please be aware that calling set_command_time on your source might break functionality since there is no out-of-order execution.

Greetings,
Marcus

Hello all!

I want to write a block that can directly access the uhd_usrp_source. This block is a mac block hence it is up on the food chain and far away from uhd_usrp_source in terms of its processing function. What is a good way of passing it a handle to the usrp_source ?

I can think of some hacks (such as a static global pointer where the uhd_usrp_source C++ object registers itself) but it seems ugly to me to take that route. Is there a better way to access global objects from within a block implementation.

Thanks in advance for any help.

Regards,

Ranga
