xTimerGenericCommand() function

Queries a timer to see if it is active or dormant. A timer will be dormant if: 1) It has been created but not started, or 2) It is an expired one-shot timer that has not been restarted. Timers are created in the dormant state. The xTimerStart(), xTimerReset(), xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and xTimerChangePeriodFromISR() API functions can all be used to transition a timer into the active state. Example usage: @verbatim // This function assumes xTimer has already been created. void vAFunction( TimerHandle_t xTimer ) { if( xTimerIsTimerActive( xTimer ) != pdFALSE ) // or more simply and equivalently "if( xTimerIsTimerActive( xTimer ) )" { // xTimer is active, do something. } else { // xTimer is not active, do something else. } } @endverbatim

Sets the ID assigned to the timer. IDs are assigned to timers using the pvTimerID parameter of the call to xTimerCreated() that was used to create the timer. If the same callback function is assigned to multiple timers then the timer ID can be used as time specific (timer local) storage. Example usage: See the xTimerCreate() API function example usage scenario.

Returns the ID assigned to the timer. IDs are assigned to timers using the pvTimerID parameter of the call to xTimerCreated() that was used to create the timer, and by calling the vTimerSetTimerID() API function. If the same callback function is assigned to multiple timers then the timer ID can be used as time specific (timer local) storage. Example usage: See the xTimerCreate() API function example usage scenario.

Queries a timer to determine if it is an auto-reload timer, in which case the timer automatically resets itself each time it expires, or a one-shot timer, in which case the timer will only expire once unless it is manually restarted.

Returns the name that was assigned to a timer when the timer was created.

Updates a timer to be either an auto-reload timer, in which case the timer automatically resets itself each time it expires, or a one-shot timer, in which case the timer will only expire once unless it is manually restarted.

Queries a timer to determine if it is an auto-reload timer, in which case the timer automatically resets itself each time it expires, or a one-shot timer, in which case the timer will only expire once unless it is manually restarted.

Returns the period of a timer.

Returns the time in ticks at which the timer will expire. If this is less than the current tick count then the expiry time has overflowed from the current time.

Retrieve pointer to a statically created timer's data structure buffer. This is the same buffer that is supplied at the time of creation.
