| <h2 id="_description">DESCRIPTION</h2>
|
| <div class="sectionbody">
|
| <div class="paragraph"><p>In-process transport allows to send messages between threads or modules inside a
|
| process. In-process address is an arbitrary case-sensitive string preceded by
|
| <em>inproc://</em> protocol specifier. All in-process addresses are visible from any
|
| module within the process. They are not visible from outside of the process.</p></div>
|
| <div class="paragraph"><p>The nature of in-process transport makes it easy to pass pointers between
|
| threads instead of actual data. This is, however, considered a bad application
|
| design and violates the scalable share-nothing architecture. If you do pass
|
| pointers among threads, synchronising thread access to shared data becomes
|
| your responsibility. Such design also prevents moving the thread into different
|
| process or machine once the need arises. As a rule of the thumb, don’t pass
|
| pointers among threads unless you know what you are doing.</p></div>
|
| <div class="paragraph"><p>The overall buffer size for an inproc connection is determined by NN_RCVBUF
|
| socket option on the receiving end of the connection. NN_SNDBUF socket option
|
| is ignored. In addition to the buffer, one message of arbitrary size will fit
|
| into the buffer. That way, even messages larger than the buffer can be
|
| transfered via inproc connection.</p></div>
