Try this: ---------------------------------------------------------------------- #include <iostream> #include <ext/stdio_filebuf.h> #include <cstdio> #include <unistd.h> typedef __gnu_cxx::stdio_filebuf<char> stdiobuf; using namespace std; int main() { FILE* p = popen ("cat", "w"); if (p != NULL) { stdiobuf p_buf (p, ios::out); ostream p_out (&p_buf); p_out << "foo\n" << "foo\n" << "bar\n" ; p_out.flush (); pclose (p); } else { cerr << "failed to open pipe." << endl; } } ---------------------------------------------------------------------- HTH -- Claudio Bley ASCII ribbon campaign (") Debian GNU/Linux user - against HTML email X http://www.cs.uni-magdeburg.de/~bley/ & vCards / \
