Detailed Description

Controls the iteration on a int file descriptor to read all data from the beginning to the current file position.

Constructor & Destructor Documentation

rpa::fd_ctrl::fd_ctrl	(	int	aFilDes,
		const visitor &	aVisit,
		size_t	aBufSz
	)			[inline]

This receive as parameter, an int file descriptor, and a visitor. This will read data from the file descriptor, in a loop, and pass each segment to the visitor.

Now we need a buffer for read/write cycles. This will be automatically freed if an exception is thrown.

Beware that the file position type might be different than size_t, if the files are 64 bits large.

If mispredict, this is an IO error.
