#include <file_config.h>

FAT_VI* ioc_getcb  (
  const char* drive);     /* Drive to get control block of */

The function ioc_getcb recieves a handle for the FAT Media control interface.

The parameter drive specifies the drive letter for which to receive the handle. The following values are allowed for the drive argument:

drive Initialized Drives
"" or NULL Default System drive as specified in the file File_Config.h
"M:" or "M0:" Memory Card drive 0
"M1:" Memory Card drive 1
"U:" or "U0:" USB Flash drive 0
"U1:" USB Flash drive 1
"N:" or "N0:" NAND Flash drive 0
"N1:" NAND Flash drive 1

The function is included in the library RL-FlashFS. The prototype is defined in the file File_Config.h.

Return Value
  • FAT_VI - on success.
  • NULL - on failure.
