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.

Constructor & Destructor Documentation

fdoutbuf()

libdap::fdoutbuf::fdoutbuf	(	int	_fd,
		bool	_close )

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.

virtual

When deleting the stream buffer, be sure to call sync(). Close the associated file if specified.
