OFstream doesnbt create directories or throw errors

brooksmoses

In the code that I'm currently writing, I've got a couple of lines approximately like the following:

fileName myFile = mesh.time().rootPath() / "output" / "datafile.dat";
OFstream myStream(myFile);
myFile << "Test!" << endl;

If the "output" directory exists, this works perfectly; the file gets created and written to just as I expect.

However, if the "output" directory does not exist, then the code silently ignores my requests -- it does not create an "output" directory, nor does it throw an error about the absence of the directory or give any indication that it isn't actually writing anything.

Is there any way to tell OFstream to create the directory? Or at least to throw an error if the directory doesn't exist? If not, what's the best way to have my code create the directory?

Thanks!
