Creating fstream object from a FILE* pointer

Question

The well known way of creating an fstream object is:

ifstream fobj(\"myfile.txt\");

ie. using a filename.

Answer 1

You cannot do that just in standard C++, since iostreams and C I/O are entirely separate and unrelated. You could however write your own iostream that's backed by a C FILE stream. I believe that GCC comes with one such stream class as a library extension.

Alternatively, if all you want is an object-y way of wrapping a C FILE stream, you could use a unique pointer for that purpose.
