A method and device for controlling the life cycle of a process

Abstract

The invention discloses a method and device for controlling the life cycle of processes to improve the host process efficiency and enable the processes to quit normally. The method comprises the steps that a father process is started; when it is detected that a son process starting condition is met, the father process begins to start a son process; when it is detected that a son process quitting condition is met or a message sent by the father process is received, the son process quits. By means of the method, the father process starting time is saved, the efficiency of the father process is improved, the son process can quit normally when the father process accidentally terminates, and the functions borne by the son process are not affected when the father process accidentally terminates.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a method and device for controlling the life cycle of a process. Background technique [0002] A process is a running activity of a program with certain independent functions on a certain data set, and is the basic unit of dynamic execution of the operating system. In a traditional operating system, a process is both the basic allocation unit and the basic execution unit. Each process has its own address space, including text region, data region and stack region. Among them, the text region stores the code executed by the processor, and the data region stores variables and processes during execution. The dynamically allocated memory is used, while the stack area stores the instructions and local variables of the active procedure call. [0003] As mentioned above, a process is a dynamic process of a program, and this dynamic is also reflected in the fact that the process has a l...

Problems solved by technology

[0005] Although the above-mentioned existing method for controlling the life cycle of a process is simple, it also has obvious disadvantages

For example, since the parent process takes time to create a child process, starting the child process directly after the parent process starts will affect the efficiency of the main process

For another example, if the parent process terminates unexpectedly before the child process is notified to exit, the child process will not exit normally.
