Charles,
First, this is pure C++ question.
iostream is supposed to be buffered. But behavior is platform dependent.
If you want to flush the buffer every line for iostreams you should use
endl.
cout << "Print something" << endl;
Please read C++ book for detail.
Thank you

======================================================================
When including shared object libraries into root, I've come across the
following peculiarity: the output seems to be buffered on a solaris4
platform. When I have a class with the following member:
Foo::Bar() {
cout << "Print something\n";
}
and execute it, nothing gets printed out. It takes a number of iterations
of the function before anything gets printed out. However, if I do
Foo::Bar() {
printf("Print something\n");
}
this prints out immediately.
I don't have this problem on a Linux system.
- is this a feature or a bug?
- if this is intentional, is there something that I can set to force the
output buffers to be flushed on every 'cout' statement?
The platform is:
uname -a: SunOS starsu00 5.6 Generic_105181-13 sun4u sparc
