http://bugs.openzim.org/show_bug.cgi?id=15 --- Comment #1 from Tommi Mäkitalo &lt;tommi(a)tntnet.org&gt; 2009-12-23 16:11:11 CET --- It does not really return a binary value but a struct, which has a ostream operator. If you want to have a ascii encoded std::string, you may want to use a std::ostringstream: std::ostringstream m; m << file.getFileheader().getUuid(); std::string myHexEncodedUuid = m.str(); If it is still needed to provide a std::string directly, I may add a small helper like toString, which does exactly this. If you just want to print it to std::cout, you can do: std::cout << file.getFileheader().getUuid(); The reason, why I did it that way is, that it is more versatile and efficient to do it that way. You should think, why or better if you really need a std::string. If I add a method toString you may do: std::cout << file.getFileheader().getUuid().toString(); This is more verbose but less efficient, since you allocate a temporary string, which is thrown away. I do not see a real advantage. -- Configure bugmail: http://bugs.openzim.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If you want to see the hex representation of a uuid do: zim::Uuid myUuid = ...; std::cout << myUuid; If you really need a std::string, use std::ostringstream: std::ostringstream s; s << myUuid; std::string hexUuid = s.str(); -- Configure bugmail: http://bugs.openzim.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
