 * @file    chqueues.c
 * @brief   I/O Queues code.
 *
 * @addtogroup io_queues
 * @details ChibiOS/RT queues are mostly used in serial-like device drivers.
 *          The device drivers are usually designed to have a lower side
 *          (lower driver, it is usually an interrupt service routine) and an
 *          upper side (upper driver, accessed by the application threads).<br>
 *          There are several kind of queues:<br>
 *          - <b>Input queue</b>, unidirectional queue where the writer is the
 *            lower side and the reader is the upper side.
 *          - <b>Output queue</b>, unidirectional queue where the writer is the
 *            upper side and the reader is the lower side.
 *          - <b>Full duplex queue</b>, bidirectional queue. Full duplex queues
 *            are implemented by pairing an input queue and an output queue
 *            together.
 *          .
 * @pre     In order to use the I/O queues the @p CH_USE_QUEUES option must
 *          be enabled in @p chconf.h.

/**
 * @brief   Output queue write with timeout.
 * @details The function writes data from a buffer to an output queue. The
 *          operation completes when the specified amount of data has been
 *          transferred or after the specified timeout or if the queue has
 *          been reset.
 * @note    The function is not atomic, if you need atomicity it is suggested
 *          to use a semaphore or a mutex for mutual exclusion.
 * @note    The callback is invoked after writing each character into the
 *          buffer.
 *
 * @param[in] oqp       pointer to an @p OutputQueue structure
 * @param[out] bp       pointer to the data buffer
 * @param[in] n         the maximum amount of data to be transferred, the
 *                      value 0 is reserved
 * @param[in] time      the number of ticks before the operation timeouts,
 *                      the following special values are allowed:
 *                      - @a TIME_IMMEDIATE immediate timeout.
 *                      - @a TIME_INFINITE no timeout.
 *                      .
 * @return              The number of bytes effectively transferred.
