shared memory in unix

Unix/linux shared memory applications and traps (2012-06-12-14:32)Tags: Linux memory classification: Linux applicationsShared memory is a piece of memory that is reserved for the system to be considered for communication between multiple processes.

Shared memory allows multiple processes to access the same memory space. It is the fastest available IPC format. It is designed to reduce the running efficiency of other communication mechanisms. It is often used in conjunction with other

Shared memory is the most useful communication method between processes and the fastest IPC format. The shared memory of two different processes A and B means that the same physical memory is mapped to the process address space of process a and

IPC forms in addition to pipelines, FIFO, semaphores, there is a shared memory area and Message Queuing. Here the main heap shared memory is introduced.The shared memory area is the fastest available in the IPC form. Once such a memory area is

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.
