Detailed Description

Function definitions for FILE system library, TFFS partitions.

Author:

D.L. Wood

These implementations are meant to work with a real TFFS file system and SIB EEPROM banks.

---

Define Documentation

#define TFFS_NUM_DIR   16

The number of directories to create on disk when formatting.

Function Documentation

unsigned int FILE_sysTffsCheck (  int  drv  )

Check consistency of a TFFS partition. Runs the DOSFS chkdsk utility on the requested TFFS partition. Only the status is checked; no repairs to the partition file system are attempted. Parameters: drv  The TFFS drive number for the bank to check. Returns: A FILE MSG code.

unsigned int FILE_sysTffsFormat (  int  drv, unsigned int  offset )

Format a TFFS partition. Formats a TFFS file system for a raw TFFS non-volatile memory bank. Both the TFFS/FTL layer and the DOSFS layer are written to the media. The offset parameter allows a portion of a media memory bank to be used by boot software. Parameters: drv  The TFFS drive number for the bank to format. offset  The offset in bytes from the bank base address at which the TFFS/FTL formatting should begin. Returns: A FILE MSG code.

Here is the call graph for this function:

unsigned int FILE_sysTffsMount (  int  drv  )

Mount a TFFS partition. Mounts a TFFS/DOSFS filesytem for use. The non-volatile memory bank must have previously been formatted with both the TFFS and DOSFS layers. Parameters: drv  The TFFS drive number for the bank to format. Returns: A FILE MSG code.

unsigned int FILE_sysTffsRepair (  int  drv  )

Attempt to repair a bad TFFS partition. Runs the DOSFS chkdsk utility on the requested TFFS partition. If an error is found by the utility, repairs to the partition file system are attempted. Parameters: drv  The TFFS drive number for the bank to repair. Returns: A FILE MSG code.
