Is it reliable to mix
cout statements with
fprintf statements in the same C++ code if
cout.sync_with_stdio() is used? Does thiscreate one single buffered file I/O stream?
In general, there is no problem using
fprintf and cout together in the sameprogram. The function
ios::sync_with_stdio is not standard to the C++ languagestreams library and is defined by a few PC platforms. Calling this function changes implementations of the predefined objects like
cout cin cerr to usea
stdiobuf instead of a
There will be some perfomance degradation, because both the
streambuf willbe buffering the output.
