RTCResult RTC_GetDateTimeAsync(
RTCDate* date,
RTCTime* time,
RTCCallback callback,
void* arg );
date |
Pointer to RTCDate , where date information will be stored. |
time |
Pointer to RTCTime , where time information will be stored. |
callback |
Pointer to the callback function. This callback is called from within the interrupt handler. |
arg |
Argument to pass to the callback function. |
If the request succeeds, it returns 0. If the request fails, it returns some numeric value other than 0.
This function asynchronously reads date and time data from the real time clock. It queries ARM7 for date and time data and returns those values without waiting for a response from the processor. To get the result from the processor, you must use the result
argument. If this function fails, no operation is performed and no user callback function is called.
Values are written to the variables specified by the date
and time
arguments asynchronously with respect to the function. Do not use these variables for anything else until a user callback function confirms the completion of this asynchronous operation.
