[section:asynchronous_socket_operations Requirements on asynchronous socket operations]
|
|
|
|
In this library, ['asynchronous socket operations] are those member functions
|
|
having prefix `async_`.
|
|
|
|
For an object `s`, a program may initiate asynchronous socket operations such
|
|
that there are multiple simultaneously outstanding asynchronous operations.
|
|
|
|
When there are multiple outstanding asynchronous [link
|
|
boost_asio.reference.read_write_operations read operations] on `s`:
|
|
|
|
[mdash] having no argument `flags` of type `socket_base::message_flags`, or
|
|
|
|
[mdash] having an argument `flags` of type `socket_base::message_flags` but
|
|
where `(flags & socket_base::message_out_of_band) == 0`
|
|
|
|
then the `buffers` are filled in the order in which these operations were
|
|
issued. The order of invocation of the completion handlers for these operations
|
|
is unspecified.
|
|
|
|
When there are multiple outstanding asynchronous [link
|
|
boost_asio.reference.read_write_operations read operations] on `s` having an argument
|
|
`flags` of type `socket_base::message_flags` where `(flags &
|
|
socket_base::message_out_of_band) != 0` then the `buffers` are filled in the
|
|
order in which these operations were issued.
|
|
|
|
When there are multiple outstanding asynchronous [link
|
|
boost_asio.reference.read_write_operations write operations] on `s`, the `buffers`
|
|
are transmitted in the order in which these operations were issued. The order
|
|
of invocation of the completion handlers for these operations is unspecified.
