Linux interprocess communication-Using shared memory The following will explain another way of communicating between processes, using shared memory. First, what is shared memory as the name implies, shared memory is to allow two unrelated processes

introduction of Shared memoryshared memory is one of three IPC (inter-process communication) mechanisms. It allows two unrelated processes to access the same logical memory. shared memory is a very efficient way to pass data between two processes

Inter-process communication in Linux (5): Shared Memory (2) The system calls MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory communication between processes.

The Unified Call uses MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory communication between processes. That is to say, each shared memory area corresponds to
