Example

[0025][First Embodiment]

[0026]Such asfigure 1 As shown, the first embodiment of the present invention provides an inter-process communication method, which is suitable for Linux devices, which includes, for example, the following steps:

[0027]S11, the process ID is acquired after the target process is started;

[0028]S13, the target process creates a socket based on the acquired process ID, and binds the socket to the target configuration file;

[0029]S15. The target process parses the target configuration file to obtain the process ID of the session target process contained in the target configuration file, and creates a session structure corresponding to the process ID of the session target process, wherein the session The structure includes the process ID of the session target process, and a socket descriptor that associates the socket of the target process with the socket of the session target process; and

[0030]S17, data sending or data receiving, for example, when the target process...

Example

[0041][Second embodiment]

[0042]Such asimage 3 As shown, the inter-process communication device 30 provided by the second embodiment of the present invention is suitable for Linux devices and includes: a process ID acquisition module 31, a creation and binding module 33, an analysis and creation module 35, and a data transceiver module 37.

[0043]Wherein, the process ID acquisition module 31 is for example used for acquiring the process ID after the target process is started; the creation and binding module 33 is for example used for the target process to create a socket based on the acquired process ID, and make the socket The socket is bound to the target configuration file; the parsing and creation module 35 is used, for example, for the target process to parse the target configuration file to obtain the process ID of the session object process contained in the target configuration file, and to create the session The session structure corresponding to the process ID of the target pr...

Abstract

An embodiment of the invention discloses an inter-process communication method and device and Linux equipment adopting the inter-process communication method. The multi-process communication method comprises the following steps: acquiring a process ID after a target process is started; creating a socket based on the obtained process ID, and binding the socket with a target configuration file; analyzing the target configuration file to obtain a process ID of a session object process contained in the target configuration file, and creating a session structure body corresponding to the process IDof the session object process; when data needs to be sent to the session object process, writing a target data packet into the socket descriptor in the session structure body; when monitoring that the session object process sends the data to the target process, reading the data packet from the socket descriptor in the session structure body. According to the method disclosed in the embodiment ofthe invention, efficient communication among a plurality of application programs in the embedded system can be realized.

Description

technical field [0001] The invention relates to the technical field of embedded devices, in particular to an inter-process communication method, an inter-process communication device and a Linux device. Background technique [0002] With the continuous advancement of technology and the open source of the Linux system, Linux devices have more and more applications. In a Linux device, different application processes have different divisions of labor, and data transmission is realized through communication between processes, that is, information is propagated or exchanged between processes. If good communication cannot be realized between the processes, the progress of the processes will be affected, and the operating efficiency of the Linux device will be affected. Contents of the invention [0003] In order to overcome the defects and deficiencies of the prior art, the embodiment of the present invention provides a Linux device and a communication method among multiple pro...
