[asio-users] asio version 0.3.2 released

[Christopher K. <ch...@ko...>]

asio version 0.3.2 has been released. It may be downloaded from the
asio sourceforge page at http://asio.sourceforge.net.
 
The main changes in this version are new socket options for multicast,
and new peek() and in_avail() operations on the Sync_Recv_Stream
concept.
 
The changes made since asio 0.3.1 are:

- Added new socket options for use with multicast, namely:
    asio::ipv4::multicast::add_membership
    asio::ipv4::multicast::drop_membership
    asio::ipv4::multicast::time_to_live
    asio::ipv4::multicast::outbound_interface
    asio::ipv4::multicast::enable_loopback
  Example programs demonstrating multicast were also added.

- Added new peek() and in_avail() operations to the Sync_Recv_Stream
  concept, which entailed the modification of the following classes:
    asio::basic_stream_socket
    asio::buffered_recv_stream
    asio::buffered_send_stream
    asio::buffered_stream

- Fixed a bug in the implementation of asio::ipv4::host_resolver where
  the arguments to get_host_by_name were passed in the wrong order.

- Added a new example program showing how to cancel a recv operation.

- Fixed a race condition in the demuxer_test unit test.
