strstream question

[Bpb]

I'm trying to use a string stored in a strstream object as the filename
parameter in the open call on an fstream object.. It requires a const
char* but no matter what I try I can't seem to get a raw pointer to the
string stored in the strstream object.. Anyone have an idea I'm overlooking?

Thanks in advance..

You just call the str() method on it.

strstream ss;
ss << "x.txt";
fstream fstr(ss.str());

Calling str() freezes the stream.

strstreams are deprecated you know (in favor of stringstreams).

ostringstream foo;
foo << "x.txt";
fstream fstr(foo.str(). c_str());
