## f_chdir

The f_chdir function changes the current directory of a drive.

    FRESULT f_chdir (
      const char* Path /* Pointer to the path name */
    );

#### Parameters

Path
  Pointer to the null-terminated string that specifies a directory to go.

#### Return Values

#### Description

The f_chdir function changes the current directory of the logical drive. The current directory of a drive is initialized to the root directory when the drive is auto-mounted. Note that the current directory is retained in the each file system object so that it also affects other tasks that using the drive. This function is available when `_FS_RPATH == 1`.

#### Example

        // Change current direcoty of the current drive (dir1 under root dir)
        f_chdir("/dir1");

        // Change current direcoty of drive 2 (parent dir)
        f_chdir("2:..");
