[0026] Functional Overview

[0027] As mentioned above, in order to solve the problem of inability to flexibly perform data interaction between processes existing in related technologies, the present invention provides an inter-process communication scheme, in which the current process stores the data sent to the target process in the memory block, and according to The corresponding relationship between the process ID and the message queue ID obtains the message queue ID of the target process; the current process determines the message queue of the target process through the message queue ID, and places the address information of the memory block in the message queue of the target process; the target process Read the address information in its message queue and read the data stored in the memory block, so as to improve the data exchange rate.

[0028] Additionally, as described below, the term "storage medium" may refer to one or more devices for storing data, including read-o...

Abstract

The invention discloses an interprocess communication method and a device thereof; wherein, the method comprises that: the current process stores the data transmitted to the purpose process in a preset memory block; the current process obtains the information formation identification which is corresponding to the process identification of the purpose process according to the corresponding relation between the preset process identification and the information formation identification; the current process determines the information formation of the purpose process according to the information formation identification and puts the address information of the memory block in the information formation of the purpose process; the purpose process reads the data stored in the memory block by reading the information formation according to the address information. With the help of the technical proposal of the invention, the data switching rate is increased by using the interprocess communication method, and point to point data switching among mulit-process can be flexibly carried out.

Description

technical field [0001] The present invention relates to the communication field, in particular to an inter-process communication method and device. Background technique [0002] At present, there are various inter-process communication methods in Unix and Linux, and the communication methods involving data interaction include using message queues, files, and shared memory for communication. [0003] The message queue supports process-to-process point-to-point communication, but this method needs to copy data, which is inefficient; using data files for communication can realize the function of exchanging data flexibly between processes, but as the process requires data exchange rate Continuous improvement, this method has great limitations; at present, more applications use shared memory for communication, this technology is suitable for large data interaction, and does not need to copy data, but this method is not very flexible , when data interaction involving multiple pro...
