Interprocess Communication Method and Interprocess Communications System

摘要

An interprocess communication (IPC) method and an IPC system for transmit communication data from a first process to a second process, where the method includes performing initialization configuration on the first process and the second process, including creating first memory space in shared memory space, selecting a communication manner based on a length of the communication data and a value of a threshold, where the threshold is a size of the first memory space, performing interprocess data exchange in the selected communication manner, selecting a memory sharing manner for communication when the length of the communication data is less than the threshold, and selecting a data file manner for communication when the length of the communication data reaches or exceeds the threshold.
