The problem with pipes, fifo and message queue – is that for two process to exchange … Interprocess supports Windows and all generic Unix-like systems. Additionally, platform-specific extensions are supported on select systems. The policy with those extensions is to put them behind #[cfg] gates and only expose on the supporting platforms, producing compile errors instead of runtime errors on platforms that have no support for those features.

Require more time consuming task of kernel intervention. 1. IPC in Shared-Memory Systems. A process creates the shared-memory region in it's own address space. Other processes communicate by attaching the address space to their own address space. Processes communicate by Reading and Writing data in the shared area.Inter process communication is a type of mechanism that allows processes to exchange useful information between them. It can be done using different methods such as … Direct Communication. Both sender and receiver must know each other’s identity. • send(Q, message): send. message to process Q. receive(P, message): receive message from process P. OS establishes link automatically when message sent. Address symmetry: both P and Q must name each other to communicate. Disadvantage is lack of discovery.
