 * \brief Print formatted data to a stream.
 *
 * Similar to fprintf() except that the format string is located in
 * program memory.
 *
 * \param stream Pointer to a previously opened stream.
 * \param fmt    Format string in program space containing conversion
 *               specifications.
 *
 * \return The number of bytes written or a negative value to indicate
 *         an error.
 *
 * \warning The function will not check, if the stream pointer points
 *          to a valid stream.
 *
 * \warning Do not use this function with a debug device while running
 *          in interrupt context.
