Description

The f_getcwd function retrieves full path name of the current directory of the current drive. When FF_VOLUMES >= 2, a heading drive prefix is added to the path name. The style of drive prefix depends on FF_STR_VOLUME_ID.

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

    FRESULT fr;
    TCHAR str[SZ_STR];

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