591 * STOP A TIMER
592 *
593 * Description: This function is called by your application code to stop a timer.
594 *
595 * Arguments : ptmr Is a pointer to the timer to stop.
596 *
597 * opt Allows you to specify an option to this functions which can be:
598 *
599 * OS_TMR_OPT_NONE Do nothing special but stop the timer
600 * OS_TMR_OPT_CALLBACK Execute the callback function, pass it the callback argument
601 * specified when the timer was created.
602 * OS_TMR_OPT_CALLBACK_ARG Execute the callback function, pass it the callback argument
603 * specified in THIS function call
604 *
605 * callback_arg Is a pointer to a 'new' callback argument that can be passed to the callback function
606 * instead of the timer's callback argument. In other words, use 'callback_arg' passed in
607 * THIS function INSTEAD of ptmr->OSTmrCallbackArg
608 *
609 * perr Is a pointer to an error code. '*perr' will contain one of the following:
610 * OS_ERR_NONE
611 * OS_ERR_TMR_INVALID 'ptmr' is a NULL pointer
612 * OS_ERR_TMR_INVALID_TYPE 'ptmr' is not pointing to an OS_TMR
613 * OS_ERR_TMR_ISR if the function was called from an ISR
614 * OS_ERR_TMR_INACTIVE if the timer was not created
615 * OS_ERR_TMR_INVALID_OPT if you specified an invalid option for 'opt'
616 * OS_ERR_TMR_STOPPED if the timer was already stopped
617 * OS_ERR_TMR_INVALID_STATE the timer is in an invalid state
618 * OS_ERR_TMR_NO_CALLBACK if the timer does not have a callback function defined
619 *
620 * Returns : OS_TRUE If we stopped the timer (if the timer is already stopped, we also return OS_TRUE)
621 * OS_FALSE If not
