Boost C++ Libraries: Ticket #9413: boost::ipc::message_queue does not support 32 process communicate with 64 process https://svn.boost.org/trac10/ticket/9413 <p> The win_msg_hdr_t, msg_hdr_t, win_mq_hdr_t, mq_hdr_t use typedef typename boost::make_unsigned&lt;difference_type&gt;::type size_type; </p> <p> The sizeof(size_type) is 32 in 32 bit process and 64 in 64 bit process. So when a 32 bit process want to communicate with a 64 bit process, the sizeof(msg_hdr_t) is not equal, which would cause process crash. </p> <p> Now I </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9413 Trac 1.4.3 huyuguang <huyuguang@…> Wed, 20 Nov 2013 09:08:43 GMT <link>https://svn.boost.org/trac10/ticket/9413#comment:1 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/9413#comment:1</guid> <description> <p> I am so sorry.
