Detailed Description

Map a file into virtual memory.

Member Function Documentation

accessMode()

access_mode v1::file_view::accessMode ( ) const

inlinenoexcept

Access mode of the opened file.

flush()

void v1::file_view::flush	(	void *	base,
		std::size_t	size )

Flush changes in memory to the open file.

Parameters

base	Start location of the memory to flush.
size	Number of bytes from the base of the memory region to flush.

loadView()

static std::unique_ptr< resource_view > v1::file_view::loadView ( URL const & location )

inlinestatic

Load a view of a resource. This is used when the resource that needs to be opened is a file.

location()

URL const & v1::file_view::location ( ) const

inlinenoexcept

URL location to the file.

offset()

std::size_t v1::file_view::offset ( ) const

inlineoverridevirtualnoexcept

Offset of the mapping into the file.

Implements v1::resource_view.

span()

const_void_span v1::file_view::span ( ) const

inlineoverridevirtualnoexcept

Span to the mapping into memory.

Implements v1::resource_view.

writable_span()

void_span v1::file_view::writable_span ( )

inlineoverridevirtualnoexcept

Span to the mapping into memory.

Implements v1::writable_resource_view.
