This change adds support for stream-oriented and random-access files.
For example, to write to a newly created stream-oriented file:
asio::stream_file file(
my_io_context, "/path/to/file",
asio::stream_file::write_only
| asio::stream_file::create
| asio::stream_file::truncate);
file.async_write_some(my_buffer,
[](error_code e, size_t n)
{
// ...
});
or to read from a random-access file:
asio::random_access_file file(
my_io_context, "/path/to/file",
asio::random_access_file::read_only);
file.async_read_some_at(1234, my_buffer,
[](error_code e, size_t n)
{
// ...
});
This feature currently supports I/O completion ports on Windows, and
io_uring on Linux (define BOOST_ASIO_HAS_IO_URING to enable).
