Abstract: Embodiments of the present disclosure relate to the field of information technology, and an inter-process communication method and a client implementing the method are disclosed. The method includes: storing, by a first process, signaling in a buffer area, and broadcasting the event to all the other processes; reading, by each of all the other processes, the signaling in the buffer area after receiving the event, and determining whether the signaling is directed to the process; when the signaling is directed to the process, performing an operation indicated by the signaling; when the signaling is not directed to the process, discarding the signaling.
