shared memory synchronization

A shared memory area is a portion of physical memory that is shared by multiple processes. If more than one process maps the region of memory to its own virtual address space, those processes can access the shared memory area directly, allowing

The so-called shared memory is the fastest available IPC form that allows multiple processes to access the same piece of memory space. is designed for inefficient operation of other communication mechanisms. It is often used in conjunction with

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

We can run various computer software programs on computers. Each running program may contain multiple independent threads ).A thread is a program that runs independently and has its own dedicated running stack. Threads may share resources with other

Shared memory is one of the simplest methods for inter-process communication. The shared memory allows two or more processes to access the same memory, just as the malloc () function returns a pointer to the same physical memory area to different
