Method mkdir

Marlin/src/sd/SdBaseFile.cpp:440–474

* Make a new directory. * * \param[in] parent An open SdFat instance for the directory that will contain * the new directory. * * \param[in] path A path with a valid 8.3 DOS name for the new directory. * * \param[in] pFlag Create missing parent directories if true. * * \return true for success, false for failure. * Reasons for failure include this file is already open, \a parent is not a

 * directory, \a path is invalid or already exists in \a parent.
