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 read
operations on s:
— having no argument flags
of type socket_base::message_flags, or
— 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 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 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.
