In this lecture on Program for Inter-Process Communication using shared memory, you will learn how shared memory is used for inter process communication in Linux using C language. • Shared Memory is the fastest inter-process communication (IPC) method. The operating system maps a memory segment in the address space of several processes so that those processes can read and write in that memory segment. The overview is as shown below: • Two functions:shmget() and shmat() are used for IPC using shared memory. shmget() function is used to create the shared memory segment while shmat() function is used to attach the shared segment with the address space of the process. • Subscribe - / dextutor • This lecture is part of the Operating System Lab playlist: • Operating System Lab • • For Program code and more details visit: https://dextutor.com/program-for-ipc-... • Reference Videos: • 1.
