FatFs APIs
The set of APIs is divided into four groups：
- Group of APIs that operates with logical volume or partition (逻辑卷或者分区操作API组).
- Group of APIs that operates with directory (目录操作API组).
- Group of APIs that operates with file (文件操作API组).
- Group of APIs that operates with both file and directory (文件和目录操作API组).
The following list describes what FatFs can do to access the FAT volumes：
- f_mount(): Register/Unregister a work area (注册/取消注册工作区).
- f_open(): Open/Create a file (打开/创建文件).
- f_close(): Close a file (关闭文件).
- f_read(): Read a file (读文件).
- f_write(): Write a file(写文件).
- f_lseek(): Move read/write pointer, Expand a file size (移动读/写指针，扩展文件大小).
- f_truncate(): Truncate a file size (截断文件大小).
- f_sync(): Flush cached data (刷新缓存数据).
- f_opendir(): Open a directory (打开一个目录).
- f_readdir(): Read a directory item (读取目录项).
- f_getfree(): Get free clusters (获取可用容量).
- f_stat(): Check if the object is exist and get status (检查对象是否存在并获取状态).
- f_mkdir(): Create a directory (创建目录).
- f_unlink(): Remove a file or directory (删除文件或目录).
- f_chmod(): Change an attribute (更改属性).
- f_utime(): Change timestamp (更改时间戳).
- f_rename(): Rename/Move a file or directory (重命名/移动文件或目录).
- f_chdir(): Change the current directory (更改当前目录).
- f_chdrive(): Change the current drive (更改当前驱动器).
- f_getcwd(): Retrieve the current directory (检索当前目录).
- f_getlabel(): Get volume label (获取卷标).
- f_setlabel(): Set volume label (设置卷标).
- f_forward(): Forward file data to the stream directly (直接将文件数据转移到数据流中).
- f_mkfs(): Create a file system on the drive (在驱动器上创建文件系统).
- f_fdisk(): Devide a physical drive (分割物理驱动器).
- f_gets(): Read a string (读取字符串).
- f_putc(): Write a character (写一个字).
- f_puts(): Write a string (写字符串).
- f_printf(): Write a formatted string (写格式化字符串).
- f_tell(): Get the current read/write pointer (获取当前读/写指针).
- f_eof(): Test for end-of-file on a file (测试文件的文件结束符).
- f_size(): Get the size of a file (获取文件大小).
- f_error(): Test for an error on a file (测试文件上的错误).
