Abstract: Embodiments of this application disclose example methods and example apparatuses for inter-process communication, and example computer storage medium One example method in embodiments of this application includes executing a first instruction, where the first instruction instructs a first process to invoke a second process. In response to executing the first instruction, a kernel switches a context of the first process to a context of the second process based on the first instruction The second process can then be executed. The first process can be an application program in a user mode or a system program in a user mode, and the second process can be a first system program in a kernel mode.
