Figure 1 File System Module Configuration
Figure 1 illustrates the file system module configuration. The libfs APIs become available by using the system calls of Cell OS Lv-2 provided by VFS (Virtual File System). The system calls provided by VFS are also used by the standard file I/O functions (fopen(), fread(), fwrite(), fclose()) provided by libc.
In addition to the standard APIs for file I/O and directory operations, libfs provides Stream Support API.
FAT accesses files on a Memory Stick™ inserted into the built-in Memory Stick™ slot via the Storage Device Driver interface.
CFS accesses files on the built-in hard disk via the Storage Device Driver interface.
DISCFS accesses files on a Blu-ray Disc inserted into the built-in optical disc drive via the Storage Device Driver interface.
HOSTFS communicates with the host file server of a host PC via the Debug interface to access files on the host PC. 引用SDK中的一张图。改文件系统是sony自己开发的基于CELL的File System,简称CFS。sony自己都没公开相关的spec,必须用他提供的专用API才可以访问。
所以目前想要开发出能够在PC***问CFS的工具还是有困难的。
期待外接硬盘NTFS还更现实一些。 |
