How does QNXs network work transparently?
QNX’s network works transparently because the Net process and its drivers extend message passing across the network. In the case of the file system, an I/O call to a file across the network is turned into a message to the Fsys on the node where the file is located. This feature extends to most system resources, and can be used by application processes equally as well. 12) What other forms of Inter Process Communication does QNX support QNX supports all the standard forms of interprocess communication, such as pipes, queues, and signals. Unlike most POSIX systems, these forms of communication can extend across the network. QNX also supports POSIX compliant shared memory. Shared memory cannot be shared across the network of course. QNX also supports shared memory with non-portable routines known as the qnx_segment..() routines. These were mostly important for 16 bit applications that could not use the POSIX shared memory routines, and require the use of large model compiler features. The
