Detailed Description

Base class for copying a file descirptor into another.

A calling program must provide an object which is used as a functor, each time a segment is mapped into memory. Thus, the loop over the segments is handled by 'mmap_ctrl'.

Member Function Documentation

virtual void rpa::visitor::visit	(	const char *	aPtr,
		size_t	aLen
	)			const [pure virtual]

Because the size if a size_t, which may have 32 bits, it is possible to map 64 bits file without the need to tell to the output stream.

Implemented in rpa::streambuf_visitor, rpa::FILE_visitor, and rpa::fd_visitor.
