How do I set up QSPY to filter a specific signal?

QS filters are not designed to filter specific event signals. Instead, QS can filter "QS records", which are defined in the qs.h header file. Examples of such records are: 


    QS_QEP_STATE_ENTRY,                      /**< a state was entered */

    QS_QEP_STATE_EXIT,                        /**< a state was exited */

    QS_QEP_STATE_INIT, /**< an intial transition was taken in a state */

    QS_QEP_INIT_TRAN,  /**< the top-most initial transition was taken */

    . . .

     QS_QF_ACTIVE_POST_FIFO,    /**< an event was posted (FIFO) to AO */

    QS_QF_ACTIVE_POST_LIFO,     /**< an event was posted (LIFO) to AO */

    QS_QF_ACTIVE_GET, /**< AO got an event and its queue is not empty */

    QS_QF_ACTIVE_GET_LAST,/**< AO got an event and its queue is empty */

    . . .


You can filter the QS records on and off by the "Global Filter". For example, you can say:


QS_FILTER_ON(QS_QEP_INIT_TRAN);

QS_FILTER_ON(QS_QF_ACTIVE_GET_LAST);


The QS filters are documented in Section 3.8.5 of the "QP Programmer's Manual" (http://www.quantum-leaps.com/doc/QP_Manual.pdf).

Thanks,
I know that you can filter records.
So it may be a nice addition to have the ability to filter events
