outputting to a file

[Ceset]

hi guys

mLog.open(errFile.c_str(), std::fstream::out|std::fstream::trunc);

as you see i create a file and open it like that. but what i dont like is the output is done not right at any output order call but after the program ends.

why is that and if there is a way to output when an output is ordered

thx in advance
