Detailed Description

Typedef Documentation

logical_drive_vector_table_t

typedef struct logical_drive_vector_table logical_drive_vector_table_t

The struct represents a table of function pointers and it used used by logical_drive_t struct, in order to call up correct functions for the file system type being used by the logical drive.

Function Documentation

fatfs_initialize()

fs_status_t fatfs_initialize

(

fatfs_logical_drive_t *const

fatfs_drive

)

This API function will initialize the fatfs_drive, by zeroing fatfs structure making it ready to be used, as well as setting vector table vtptr inside base to point to functions relevant for FatFs operations. It also sets type inside base struct to be FS_TYPE_FATFS, signaling at the same time that logical drive is initialized and that its type is FatFs. All other values are set to zeros.

Postcondition

Logical drive fatfs_drive is now ready to be used by filesystem.
