Method for operating writing-file

Abstract

The invention discloses a method for writing a file operation. The basic idea of ​​the invention is to establish a unified management file operation task. When the system task needs to write a file operation, a request for writing a file is initiated to the file operation task; the file operation task Divide the information to be written into small blocks, and write the file in units of blocks. After writing the unit block information, judge whether the write operation flag is terminated. If not, continue to write the next piece of information. If yes, stop writing Operation; if you want to terminate the write operation during the file writing process, send a request to terminate the write file, and set the write operation flag to terminate. The invention can divide the information to be written into small information blocks, and can terminate the file writing operation during the information writing process.

Description

technical field [0001] The invention relates to file operation technology, in particular to a method for writing file operation. Background technique [0002] File operation technology is widely used and is often used in technology development and equipment operation, such as log file records, data configuration file records, and other information records. Many information in the memory must be written into files. [0003] The existing operation method for writing files is to continuously write information into the file, specifically after opening the file, continuously call the write function to write the information into the file, until all the information is completely written, and finally close the file; and, the existing The write file operation is scattered among many tasks of the software running system. [0004] As can be seen from the above prior art, the existing file writing operation has the following disadvantages: [0005] 1) Because it is a method of continu...

AI Technical Summary

Problems solved by technology

When a large message is writing a file, if the user wants to terminate the operation of writing the file midway, such as issuing a command to terminate the current execution, or wishing to stop the writing operation of the file before the system is reset, the purpose cannot be achieved

[0006] 2) When there is currently a file writing operation, if the system is reset, the file writing operation is forcibly interrupted, which may cause file loss, damage to the file system, or even cause system crashes

[0007] 3) The direct operations on files are scattered in each module of the software operating system, which is inconvenient to manage the operations of files uniformly
