Preallocate ostringstream buffer

Tech-Archive recommends: Fix windows errors by optimizing your registry

Dear All,

I want to write about 8Mb of data to a ostringstream and I do not want the
stream continually reallocating ever larger chunks of memory as the data is
written.

With ostrstream I can map the stream onto a preallocated buffer, eg.

char *buffer = new char[length];
ostrstream os(buffer, length);

Is a this possible with ostringstream?

Regards,
Andrew
