fstream

is there way to retreive the file name from this:

Code:

---

ifstream f ("test.txt");

---

here, how can i retreive the filename of the opened file?
thanks

You can't. Why would you want to?

well..i have a function that receives the name of a file..i use this to initilaze a stream, and then later on, instead o using the passed value i wanted to retreive it from the stream...but indeed taht is useless..i'll just use the passed value
