Detailed Description

For writing into an output streambuf.

Necessary because the data may not be written in one go, if it requests too much mapped memory. So, 'mmap_ctrl' takes this object, maps the file piece by piece, and calls the visitor each time a segment is mapped.

(

strmbuf_t *

aStrmBuf

)

[inline]

The streambuf is used later : The functor writes into it the content of a segment.

Member Function Documentation

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

This is called for each segment of file mapped into memory. It is not possible to assume that all the file can be mapped in one go.

Implements rpa::visitor.
