Additional functions

To get the current working directory, use

f_getcwd(TCHAR *, UINT);

To use this function, we have to change the configuration in conf_fatfs.h. Set #define _FS_RPATH to 2. '

To open a dir,

f_opendir(DIR*, const TCHAR *);

Declare the 2nd parameter as a array and not a pointer, i.e

const TCHAR path[100];
//const TCHAR *path;

To get a pointer to a directory object,

f_opendir (DIR*, const TCHAR*);

and to read a directory item,

f_readdir (DIR*, FILINFO*);

f_readdir return FR_OK when it successfully reads an item.

Note: remember to initialize the variables for DIR and FILINFO to 0 using memset.
