No.  You should should stick this info into the dict in do_info_spice, 
then just get it from the dict for printing like it is done for auth. 
This way you'll have the information in the qmp monitor too.

I think it would also be nice to somehow hint this is the spice version 
qemu was compiled against.  The shared library which is actually used 
might be newer.

cheers,

sent a second patch (fixing the above), but didn't do any hinting. I'll send a third.

I thought of this problem but decided it's better to at least have the compiled
version (getting the linked against version is not hard, but I'd rather
not force to do it at this moment - I guess via dlopen. Which is linux specific - 
will need yet another wrapper for that api to compile on windows).

Hi,

Saw v2.  I would just stick a "version" string into the dict instead of 
the three values for major, minor and micro.

The compiled version is perfectly fine, I think it is more useful to 
have that one as it decides which features qemu is able to use.

If we want report the runtime version too (any reason to do this?) I'd 
just add a spice_server_get_version() function to the library.

cheers,

Argh. Sent v3 with the three ints. Do you prefer a single version?

Just completeness :) I'm not going to do it right now anyway.

Yea, would be great.
