There is also
https://git.gnome.org/browse/gupnp-tools/tree/src/discover/gssdp-discover.c

To see what kinds of queries are possible, See UDA1.1[1] pg. 32, ST
header description.

If you need specific examples, see the light-client example or the av-cp
from gupnp-tools.

You can search for
 - ssdp:all
 - upnp:rootdevice
 - specific device types with or without minimum version such as
urn:schemas-upnp-org:device:MediaServer:1
 - specific service types with or without minimum version such as
urn:schemas-upnp-org:service:BasicManagement:2

But since this is merely a string comparison, you can basically search
for anything your peer provides.
