how can i get the ofstream file name

Hello all
it seams to be beginners question , but do i have the possibility to get the
file name i set in the ofstream constructor?

Considering that you set it, obviously you know it, so you just need to save it.

i meant ou tof the ofstream variable
if i have
ofstream file("foo.txt")
how can i get from file variable the "foo.txt" string

You cannot do that.

You could of course define your own class that stores the name of the file before opening an ofstream, and then make a ofstream cast-operator that returns the actual ofstream.

But there is absolutely no standard way to get the filename out of a stream, and I know of no implementation of file-streams that actually store the filename as part of the stream object.
