Detailed Description
fdoutbuf is a stream buffer specialization designed specifically for files that are referenced using a file descriptor. This class implements a 4k buffer for data and optionally closes the file when the buffer is deleted.
- Note
- Instead of using this class, use fdostream.

Make an instance of fdoutbuf. To write to a file using an open file descriptor, use fdostream instead.
- Parameters
-
_fd The open file descriptor _close If true, close the file when the stream buffer is deleted. False by default.
