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

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.

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

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

Source Http://www.blogjava.net/sunzhong/articles/297435.html The shared memory area is a part of the physical memory shared by multiple processes. If multiple processes map the memory area to their virtual address space, these processes can

Linux inter-process communication (IPC) Programming Practice (7) use of shared memory-System V shared memory (API) The system call mmap mentioned in the previous blog map a common file to implement shared memory. The System V shared memory described

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

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

Today Mayuyu to learn one of the important things in Linux, namely shared memory . We know that there are various IPC communication mechanisms available in Linux, such as signals, semaphores, pipelines, message queues, shared memory, and sockets. It

Shared memory is the fastest and most efficient form of interprocess communication, and when shared memory is mapped to the address space of a process that shares it, the data transfer between processes is no longer involved in the kernel, and the

Here's another way to explain interprocess communication, using shared memory.One, what is shared memoryShared memory, as the name implies, allows two unrelated processes to access the same logical memory. Shared memory is a very efficient way to

A shared memory introduction shared memory can be literally understood,share a piece of logical memory, let different processes access it, modify it。 Shared memory is a very efficient way to share and pass data between two running processes. Memory

Reprint Please specify the Source: http://blog.csdn.net/suool/article/details/38515863shared memory can be described as a mapping of an area ( segment) of memory that can be shared by more processes. This is the fastest form of the IPC mechanism

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.

In interprocess communication mode, each IPC object has a unique name, whether it is using message queue, shared memory, or even semaphores, it is called a key ). Through the "key", the process can identify the objects used. The relationship between
