Hi,

For my game, I would like to format strings. I know how to do this in C,
using varargs and vstrnfmt, etc, but I'm writing the game in C++. I'm
trying to use the "strstream" class which seems to do what I want, but
there are problems reading the string back.

Basically, the strstream class is similar to other stream classes in
that you can use insertors and extractors. Then you use the function

  char *str();

to read the string you have created. However, the string doesn't seem to
be null terminated, and I don't want to write  string << [...] << '\0';
all the time. Also, I can't find how to erase the string.

So, my question:

1. Has anybody any advice for using the strstream class? It seems to do    
   what I want but I can't get it to work.

2. Is there any other way to create formatted strings? My game uses a 
   lot of text (it's a Roguelike) which changes a lot, so formatting 
   strings is important. I like the look of the strstream class because
   you can use the C++ insertors without worrying about %d and %f 
   symbols...

Thanks very much for your help, and bye for now,
