Re: binary file output

You can use the C open/write/close statements. This is in general machine dependent and also depends if you want to write small (< 2 GBytes) or large files. See examples in ROOT class TFile
http://root.cern.ch/root/htmldoc//src/TFile.cxx.html

eg in TFile::Open see the statements

    // Connect to file system stream
    if (create || update) {
  .....

Look also at the bottom of the page at static functions TFile::SysOpen, SysClose, SysWrite
