436 * FIND OUT WHAT STATE A TIMER IS IN
437 *
438 * Description: This function is called to determine what state the timer is in:
439 *
440 * OS_TMR_STATE_UNUSED the timer has not been created
441 * OS_TMR_STATE_STOPPED the timer has been created but has not been started or has been stopped
442 * OS_TMR_COMPLETED the timer is in ONE-SHOT mode and has completed it's timeout
443 * OS_TMR_RUNNING the timer is currently running
444 *
445 * Arguments : ptmr Is a pointer to the desired timer
446 *
447 * perr Is a pointer to an error code. '*perr' will contain one of the following:
448 * OS_ERR_NONE
449 * OS_ERR_TMR_INVALID 'ptmr' is a NULL pointer
450 * OS_ERR_TMR_INVALID_TYPE 'ptmr' is not pointing to an OS_TMR
451 * OS_ERR_TMR_ISR if the call was made from an ISR
452 * OS_ERR_TMR_INACTIVE 'ptmr' points to a timer that is not active
453 * OS_ERR_TMR_INVALID_STATE if the timer is not in a valid state
454 *
455 * Returns : The current state of the timer (see description).
