User Mode and Kernel Mode Shared Memory under Linux
Hao Chen · Computer Programming Skills & Maintenance · 2011
Shared memory is the most simple of the Process communication.Shared memory allowed two or more process visit the same piece of memory.as like as function malloc(),It towards to the different process return a pointer of point to the same physics memory area.Because all of the process shared the same memory,shared memory is the top efficiency of all kind of process Communication.This paper principally introduction implementation base on Netlink mechanism user mode and kernel mode shared memory under Linux.
