Thread: unbuffer fstream

Code:

file.rdbuf()->pubsetbuf(NULL,0);

Doesn't work here. I've read it is not guaranteed on all platforms. Am I better off using FILE* if I want unbuffered file output on linux?

I would question why you need unbuffered file output when you already have full control with "flush".

Well, mostly so I do not have to call flush every time.

Anyway, I dealt with this by using a wrapper that will call flush every time. Just curious (for future reference) if there is a way to set the stream unbuffered to start with.

There's the unitbuf flag - C++ I/O Flags [C++ Reference]

Doing it yourself would better.
