Only part of the code is pasted, so there is no way to run the test. In addition, your description of the problem scenario is too general. Please organize your language to describe it clearly.

Just looking at this part of the code, I don’t know what you are using for communication.. I assume it is tcp socket
These APIs, including tcp socket, are all byte stream oriented, and there is no guarantee that one write corresponds to one read.
If you want one write and one read, that is, "message" oriented, you need to implement it yourself in the upper layer.
