#include <nitro/rtc.h>RTCResult RTC_GetTimeAsync(
RTCTime* time,
RTCCallback callback,
void* arg );
This function asynchronously reads time data from the real time clock.
It queries ARM7 for time data and returns those values without waiting for a response from the processor.
To get the actual time information 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 RTCTime specified by the time argument asynchronously with respect to the function. Do not use this variable for anything else until a user callback function confirms the completion of this asynchronous operation.
time |
Pointer to RTCTime where time information will be stored. |
callback |
Pointer to specific RTCCallback function to be used. |
arg |
The argument to be passed to the Callback function. |
If the request succeeds, it returns 0.
If the request fails, it returns some numeric value other than 0.
