Returns TRUE on success or FALSE on failure. To retrieve extended error information, call the osGetLastError function.

This function resets the timer without stopping its operation.

A timer is initialized and started using the osSetTimer function, which defines the duration of a single timing cycle. During this cycle, the timer remains in the non-signaled state. Upon the completion of the cycle, the timer transitions back to the signaled state.

Timing cycles may be repeated for a specified number of iterations. After each cycle concludes and the timer is reset, the internal pass counter is incremented.

To initiate a subsequent cycle, the timer must be reset. This occurs either manually via the osResetTimer function or automatically, depending on the timer's configuration. Manual-reset timers require an explicit call to osResetTimer to start the next cycle. In contrast, auto-reset timers begin the next cycle immediately after the previous one expires. When multiple tasks are pending on an auto-reset timer, only the highest-priority task is released at the end of each cycle.

If osResetTimer is invoked while a cycle is currently in progress, the cycle is restarted from its beginning. The pass counter is only incremented upon the successful expiration of a full cycle. A cycle can be restarted indefinitely; however, the function will fail if it is called on a timer that has already stopped. In such instances, the system sets the last error code to ERR_TIMER_NOT_STARTED.

For additional details regarding timer behavior and management, please refer to the Timer Objects section.

This function is available only when the OS_USE_TIMER configuration constant is set to 1.
