Abstract

A communication method, system, device and computer-readable storage medium are applicable to a Windows system. The method involves: determining a media file used when communicating through a message queue; acquiring identification information of a communication sender; and adding the identification information to an access control list of the media file, such that the communication sender can access the media file, so that the communication sender can communicate through the message queue. Identification information of the communication sender is added to the access control list of the media file, increasing the probability that the communication sender successfully accesses the media file, and thereby improving the success rate of the communication sender through the message queue, and improving the communication stability of the Windows system.

First claim

The invention claimed is:

1. A communication method, applied to a Windows® system, comprising:
determining that a communication is performed through a message queue for the first time;
determining a media file used when communicating through the message queue;
determining if identification information of a communication sender exists in an access control list of the media file by acquiring an access control entry (ACE) instance of a current discretionary access control list (DACL) from the access control list and determining if the identification information exists in the ACE instance;
acquiring identification information of the communication sender when the identification information does not exist in the ACE instance;
acquiring a security descriptor of the media file and generating a new security descriptor based on the security descriptor;
adding the identification information to the access control list, such that the communication sender can access the media file, so that the communication sender can communicate through the message queue;
setting the access control list in the new security descriptor;
setting the new security descriptor in a corresponding file; and
performing a memory release operation to release corresponding memory.

2. The method according to claim 1 , wherein after the adding the identification information to the access control list of the media file, the method further comprises:
prompting the communication sender to communicate through the message queue.

3. A communication device, applied to a Windows® system, and comprising:
a memory, configured to store a computer program; and
a processor, configured to execute the computer program to implement the steps of the communication method according to claim 1 .

4. A non-transitory computer readable storage medium, applied to a Windows® system, the non-transitory computer-readable storage medium storing a computer program, the computer program being executed by a processor to implement the steps of the communication method according to claim 1 .
