[0002] Android R introduces the mechanism of the Fuse file system. When an APP (application) reads and writes files, according to the design of the fuse file system, every time a file is read or written, the module in the kernel mode must interact with the multimedia application in the user mode for confirmation. The larger the file, the more interactive tests, the more time-consuming, and the lower the efficiency of file reading and writing

The invention discloses a file reading and writing method, a terminal and a computer readable medium, and the method comprises the following steps: obtaining a file handle and process information when a reading and writing request of a file is monitored; and according to the obtained file handle and the process information, directly reading and writing the file through a bottom-layer file system. According to the technical scheme, when a reading and writing request of the file is monitored, the file handle and the process information is acquired. the file is read and written directly through a bottom file system according to the obtained file handle and the process information; and the read-write request of the file does not need to be processed through user-mode multimedia application processing, so that the continuous writing efficiency of the file is greatly improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a file reading and writing method, a terminal and a computer-readable medium. Background technique [0002] Android R introduces the mechanism of the Fuse file system. When an APP (application) reads and writes files, according to the design of the fuse file system, every time a file is read or written, the module in the kernel mode must interact with the multimedia application in the user mode for confirmation. The larger the file, the more interactive tests, the more time-consuming, and the lower the efficiency of file reading and writing. Contents of the invention [0003] The main purpose of the present invention is to provide a method for reading and writing files, a terminal and a computer-readable medium, aiming at effectively improving the efficiency of reading and writing files. [0004] In order to achieve the above object, the file reading and writing method p...
