Can I remove bytes from a (o)fstream object?

[Jantje Smit]

I was wondering how to remove bytes from a binary file, if
possible. I looked up the member functions of fstream (and
ofstream), and no functions are provided to remove bytes
from the stream (AFAIK).

Does this mean, the only way to remove a part of a file, is
to rewrite the file to disk, but without the removed part?!?
(I could do that, but I just wrote an insertion function,
which allows me to insert bytes in a file stream without
having to close and reopen the file stream, and would like
to have such an option for deletion as well)

Can anyone enlighten me on this?

Many thanks,
Dede

Your OS may have a solution for the same.
