FatFs - f_getcwd

## f_getcwd

The f_getcwd function retrieves the current directory of the current drive.

    FRESULT f_getcwd (
      TCHAR* buff, /* [OUT] Buffer to return path name */
      UINT len     /* [IN] The length of the buffer */
    );

#### Parameters

buff
  Pointer to the buffer to receive the current directory string.
len
  Size of the buffer in unit of `TCHAR`.

#### Return Values

FR_OK, FR_DISK_ERR, FR_INT_ERR, FR_NOT_READY, FR_NOT_ENABLED, FR_NO_FILESYSTEM, FR_TIMEOUT, FR_NOT_ENOUGH_CORE

#### Description

The `f_getcwd` function retrieves full path name of the current directory of the current drive. When `FF_VOLUMES` is larger than 1, a logical drive number is added to top of the path name.

Note: In this revision, this function cannot retrieve the current directory path on the exFAT volume. It always returns the root directory path.

#### QuickInfo

Available when `FF_FS_RPATH == 2`.

#### Example

        TCHAR str[256];

        fr = f_getcwd(str, sizeof str / sizeof *str);  /* Get current directory path */
