Swap the file contents

[jayfriend]

Hi All,

I would like to swap the contents of two large files without using any temporary file. However, a buffer can be used instead of temporary file. I could swap the file contents, but have a problem in deleting the contents of the larger file at the end.

Please help resolve this problem.

Thanks in advance.

Clear the large file before writting to it from the bufffer

Could read the file contents into a vector as well.
