Triming characters off the end of a stream

I have a strstream, which has a few characters at the end of the stream ')|'
to be exact, I want to remove them form the stream, but SetLength doesn't
work on strstream, and I can't find any other way to turnicate the stream.

There is no direct way to truncate a strstream. You will have to copy the

desired portion of it to another stream or other container and then perform
the rest of your operations on that. For example:
strstream data;
// fill data as needed, then...
strstream tmp(data.str(), NumberOfCharsToKeep);
// use tmp as needed...

Guess that means unless I want to decrease performance I should just fix the

function. Thanks Remy.
