Hi,
I have an app that generates a text log at a very high rate. Currently
I use an ofstream object to write the log. I would like to control when
'exactly' the log is written to the disk. Also I want to be able to
reset the buffer contents without writing them to the disk file.
- Can the 'buffer size' of an ofstream object (in fact, any iostream
lib object) be controlled?
- Can we control *when* the buffer is flushed? [I want ofstream to
flush *only* when I invoke flush(). The default 'nounitbuf' behavior
doesn't do what I want]
- Is there a way to *reset* the ofstream buffer?
Thanks,
Ishan.
