Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
I'd like to initialize my RNG (rand num generator) with different seeds at different times (I submit many jobs with the same inputs). I use the following on Linux:
CLHEP::HepRandom::setTheEngine(new CLHEP::RanecuEngine); std::fstream randomFile; randomFile.open("/dev/urandom", std::ios::in | std::ios::binary); unsigned int seed; randomFile.read(reinterpret_cast<char *>(&seed), sizeof(unsigned int)); randomFile.close(); G4cout << "Random seed is " << seed << G4endl;
--- now, the question is: how i'm gonna code it on Windows where /dev/urandom is not available. we need a portable code for this very common task.
