Information transmission methods, electronic devices, and storage media

Abstract

This application discloses an information transmission method, an electronic device, and a storage medium, and relates to the field of computer technology. The method includes: a master thread of a first process creating a first child thread and a second child thread, the first child thread being callable by the master thread via a first function and not callable by the master thread via any function other than the first function, the second child thread being callable by the master thread via any function other than the first function, one of the first and second functions being used to send window information to a second process and the other being used to instruct the second process to release buffer space. The master thread operates the first function to transfer first target information to the first child thread. After receiving the first target information, the first child thread sends the first target information to the second process. In this application, an abnormal state of one of the first and second functions does not affect the operation of the other. This avoids performance problems caused by abnormal conditions in the first or second function.
