[0034] The preferred embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0035] The present invention provides an interface system for accessing file system in user space, such as figure 1 As shown, it includes a dynamic link library 101, a shared memory module 102, an agent process module 103, and a data storage module 104; the dynamic link library 101, the shared memory module 102, the agent process module 103, and the data storage module The modules 104 communicate sequentially. The dynamic link library 101 is used to provide a file system access interface and is embedded in the application process address space to run. Its naming is very similar to the standard file system interface. It can be used normally only by using macro replacement and recompiling and linking. Inside the interface function, the purpose of accessing the file system is achieved by accessing the shared memory. The shared memory modul...
