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.

Inux system Programming I've been looking at the Original link http://www.cnblogs.com/skyme/archive/2011/01/04/1925404.htmlShared memory is a piece of memory that is reserved for the system to be considered for communication between multiple

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

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

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.

Reprinted from http://www.ibm.com/developerworks/cn/linux/l-ipc/part5/index2.html 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

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

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

System V shared memory is similar to POSIX shared memory, and System V shared memory is called the Shmget function and the Shamat function.The Shmget function creates a shared memory area, or accesses an existing memory area, similar to the system

Shared memory-related knowledge Shared memory is the common use of the same piece of physical memory space between multiple processes, and it is achieved by mapping the same piece of physical memory to the virtual space of different processes.
