You could use filtering_ostream with underlying vector and reserve() on that vector.

Szymon,

Thank you that is exactly what I did:

#include #include #include <string>

std::string Result;

Result.reserve(99999);

boost::iostreams::filtering_ostream Stream( boost::iostreams::back_inserter(Result));

Stream.write(pBuffer, 99999); // this part is more complicated in my real scenario

Ah, of course you used string directly. May I ask tho: why are you using a stream to write a block of memory to a string? Why not just directly copying it to a vector (or a string)? If there are no filters attached to a filtering_stream then you just add overhead/complexity without any benefit. Cheers, Simon
