Inter-process communication method, electronic device and readable storage medium

Abstract

The present invention provides an inter-process communication method, an electronic device and a readable storage medium, the method comprising: creating a service thread; creating an asynchronous named pipe handle and overlapping IO; passing the named pipe handle to the Pointer field of the overlapping IO; calling ConnectNamedPipe function; asynchronously waiting for an asynchronous task from a client; calling GetLastError function; and getting current connection state of the named pipe handle; when the current connection state is ERROR_IO_PENDING, storing the overlapping IO in a storage space; when the current connection state is ERROR_PIPE_CONNECTED, determining a first client connected with the named pipe handle, and processing the data task corresponding to the first client; after thetask is processed, if the current connection state of the named pipe handle is ERROR_IO_PENDING, storing the overlapping IO in the storage space; checking overlapping IO in the storage space throughservice thread loop, if it is checked that the current overlapping IO processing is completed, continue to process the overlapping IO of the next storage space.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an inter-process communication method, electronic equipment and a readable storage medium. Background technique [0002] Under the Windows system, the named pipe NamedPipe can be used for inter-process communication. When using named pipes to implement inter-process data transmission, both asynchronous and synchronous methods can be used. If a synchronous method is used, when sending or receiving a large amount of data, it is very likely to cause blocking or freezing of the upper-layer application. When using asynchronous transmission, since the upper layer application will not return until all the data is processed, using named pipes for asynchronous transmission will have a better effect. When using named pipes in the prior art, most of them adopt a one-to-one manner, that is, communicate between a single process and a single process, and do not adopt a manner of communic...
