Hi, I have started to use the Boost iostreams library in one of my projects. I am using the latest Boost version, 1.46.1 with a 64-bit Linux OS on a x86-64 architecture. When I compile and run the small program below, "HeavyArtillery2.txt" is created, but "HeavyArtillery1.txt" is not, and I don't understand why. Am I missing something obvious? #include <boost/iostreams/stream.hpp> #include <boost/iostreams/device/file.hpp> namespace io = boost::iostreams; int main(int argc, char *argv[]) { io::stream<io::file> out1; out1.open("HeavyArtillery1.txt"); out1 << "Reach at that Arrogance which needs thy harm,\n" "And beat it down before its sins grow worse.\n"; out1.close(); io::stream<io::file_sink> out2; out2.open("HeavyArtillery2.txt"); out2 << "Reach at that Arrogance which needs thy harm,\n" "And beat it down before its sins grow worse.\n"; out2.close(); } -- Wim van der Meer
