What is the equivalent in windows? /dev/null seems not to work properly.
Is it std::ofstream outfile('NUL')?
Not certain of this, but I would expect that you can simply default
construct an ofstream without specifying a file name.
Yes, but that will result in an error; typically, an output
error will cause the code to fail. (Output errors are normally
fairly serious, except for secondary output, like logging.)
It's pretty simple to define a nulstreambuf, which emulates the
behavior of '/dev/null' exactly. (EOF for all reads, success
for all writes.) Then just create an ostream with this as the
streambuf.
