The socket system call is, int socket (int domain, int type, int protocol); The first parameter to the socket system call is the domain. The domain is actually the communication domain and …

D-Bus is a mechanism for interprocess communication for Linux systems. D-Bus concepts along with example client-server programs are explained.
1.0 Shared Memory Shared memory is an inter process communication (IPC) mechanism in Linux and other UNIX-like systems. Based on input parameters, the kernel provides a (shared) memory segment to the calling process. The calling process maps the shared memory segment to its address space. This way, the same shared memory segment can be mapped …
POSIX message queue calls for interprocess communication (IPC) between processes are explained with an example of server and client programs in C under Linux.
1.0 Message queues Message queues are one of the interprocess communication mechanisms available under Linux. Message queues, shared memory and semaphores are normally listed as the three interprocess communication mechanisms under Linux. Semaphores, though, are really for process synchronization. In practice, shared memory, aided by semaphores, makes an interprocess communication mechanism. Message queues is the …
