Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] refer to figure 1 , shows a flow chart of the first multi-process management method of the present application.

[0043] Step S11: apply for at least one shared memory space in the memory, register the shared memory space and define processes for reading and writing to the shared memory space.

[0044]For each process, the process is first loaded into the corresponding memory space before running. In an embodiment of the present invention, the current file download process and another process are respectively loaded into two memory spaces. Apply for a shared memory space by calling the following API functions:

[0045] #include

[0046] #include

[0047] int shmget(key_t key , size_t si...

Abstract

The invention provides a multi-process interaction method and a multi-process interaction system. The method comprises the following steps that at least one shared memory space in a memory is applied for and registered, and a process for read operation and write operation over the shared memory space is defined; first message data is written for requesting for the running of the process into the shared memory space by using another process; a current file downloading process reads the first message data from the shared memory space, compares the first message data with a first mapping file in the memory, and acquires and executes an instruction; the another process writes second message data for ending the running of the process into the shared memory space; the current file downloading process reads the second message data from the shared memory space, compares the second message data with a second mapping file in the memory, and acquires and executes an instruction. According to the method and the system, the downloading process and the another process are automatically switched, and loads of the downloading process and the another process are balanced.

Description

technical field [0001] The present application relates to a multi-process interaction method and system. Background technique [0002] Downloading is a network activity that transfers files through the network and saves information on the Internet or other electronic computers to the local computer. The current download methods mainly include WEB download, BT download, P2P download and so on. [0003] If it is necessary to pause or limit the download speed to run other processes during the running of the download process, such as playing video or testing the network speed, at present, the download process is paused or the download speed is reset mainly through manual settings, resulting in the gap between processes. Switching takes a long time. Contents of the invention [0004] The technical problem to be solved in this application is to provide a multi-process interaction method, including: [0005] Applying for at least one shared memory space in memory, registering ...
