Better to use std::string or std::stringstream

Hi,

I have a "printf" style function:

void myclass::write (int, char *, ...)

This function takes the usual printf style params. The conversion I am doing is using the simple vsprintf. After the string is converted, it needs to be stored for later printing (through a std::cout interface). After the strings are converted there is no more processing done on them; they are just printed.

1. Is it better to store the strings in std::string?
2. Is it better to store the strings in std::stringstream?
3. Is there a better storage for this?


Thanks.
