Signal communication signal transmission capture Kill (), raise (), alarm (), pause () and its basic experiments Signal overview The signal is a simulation of the interrupt mechanism at the software level. In principle, a process receives a signal and the processor receives an interrupt request that can be said to be the same. The signal is asynchronous, a process does not have to do anything to wait for the signal to arrive, in fact the process do

Recently a project to use point file transmission, I find information everywhere to write procedures, and finally completed, in order to let others take less detours, I decided to the most important part of the program to contribute out, I hope to help. My program is divided into three parts, including the sending part, the acceptance part and a shared communication base class, this base class is my painstaking crystallization: First, the

Shared Memory: It is the most efficient communication mechanism in the System V version that allows multiple processes to share the same address space, and if a process modifies that address space, other processes that share the address space can see it at the same time, but it does not provide synchronization and mutex. The general combination of semaphores to achieve synchronization between the process of mutual exclusion.Create shared memory: int s
