Hello everyone, After reading Tomas Karasek's mail, I found libasyncns too. This afternoon, I hacked a python binding while I was on a train (and some hours after that), and I'm now able to use libasyncns from python. Currently, it's not very clean (currently it's a first draft), it's using swig (so we can see some "garbage" from python, like wrappers, but it has some interesting features too). Anyway, I'm able to do the same things than the "asyncns-test.c" file from the libasyncns' documentation [1] (but in ~25 lines instead of ~125) (see the file asyncns-test.py). I'm joining the code with this mail, if someone is interested. For example, it may be used to test how gajim may work with libasyncns someday (but I don't know what gajim needs). (I didn't put licensing information already but it's LGPL2+, like the libasyncns library) Keep in mind that this is a work in progress, currently: - exceptions should work - IPv6 isn't available in getnameinfo - I don't store values from requests so I can't use a query object twice - some functions are not implemented: asyncns_getnext(), asyncns_getnqueries(), asyncns_getuserdata(), asyncns_setuserdata(), asyncns_res_search(), asyncns_fd()... - this is not deeply tested, and for example I don't know how memory is managed [1]: http://0pointer.de/lennart/projects/libasyncns/doxygen/asyncns-test_8c-example.html Regards, -- Damien Thebault Key C15AB8AF Fingerprint 8FB9 8576 7033 4B45 3DF5 88E8 5471 1A44 C15A B8AF
