Hello, everyone.

A simple project with the following code creates a file blah.txt and
puts "blah" in it:

#include <fstream>
void main()
{
std::ofstream my_file ("C:/blah.txt", std::ios::app);
my_file << _T("blah") << std::endl;
my_file.close();
}

However, when I put exactly the same code in a huge multithreaded
application, an empty file gets created, but nothing ever gets written
to it. If the file already exists, this code won't add "blah" to it
either.

I am using Visual C++ 5 with service pack 3 and Windows 2000.

I've tried doing my_file.clear(); right after opening it to clean the
possible error flags, but that did not help.

Any help is appreciated.
