fat.ReadInfo

#include <file_config.h>

BOOL ReadInfo  (
     Media_INFO* cfg);      /* Structure to store the info */

The function ReadInfo reads the media configuration into a structure. With this information, RL-FlashFS checks for Storage Media compatibility, and can format the media.

The parameter cfg is a Media_INFO pointer specifying the structure to store the media configuration information (block_cnt, read_blen, write_blen).

The function is part of the FAT Driver. The prototype is defined in the file File_Config.h. Developers must customize the function.

• __TRUE - on success.
• __FALSE - on failure.
