I. Inter-process communication overview process communication has the following purposes: A. data transmission: A process needs to send its data to another process, the sent data volume is between one byte and several MB. B. shared data: if multiple

1. Mutual exclusion Lock (volume) and condition variableBy default, mutexes and condition variables are used for inter-thread synchronization, and can be used for inter-process synchronization if they are placed in a shared memory area.1.1 Mutual

This article mainly introduces the use of variable parameter functions, analyzes its principles, how programmers implement and encapsulate them, and finally possible problems and preventive measures.Variable Argument function, a variable number of

Shared memory can be said to be the most useful inter-process communication and the fastest form of IPC. Two different processes A, B shared memory means that the same piece of physical memory is mapped to the respective process address space of

Inter-process communication IPC is the abbreviation for interprocess communication, which refers to the various ways of messaging between different processes running on an operating system, and in the evolution of the UNIX operating system over

HiSilicon latest out of an ultra-low memory chip hi3518ev201 (memory only 32M)In the development process of the kernel of the cutting test is quite large, of course HiSilicon also provides a reference to the cutting scheme

 Shared Memory-memory ing MMAP Shared memory is the most useful method for inter-process communication 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

Advantages of shared memory: 1. Data is transmitted between processes without passing through the kernel, that is, data is copied without calling the system to achieve fast and efficient data transmission. 2. continued with the kernel * Nix
