## Elements

RTC_RESULT_SUCCESS | Indicates that the process completed normally.
RTC_RESULT_BUSY | Indicates that the request could not be performed because another RTC operation was being processed at the same time.
RTC_RESULT_ILLEGAL_PARAMETER | Indicates that the request was not performed because the specified parameter was illegal.
RTC_RESULT_SEND_ERROR | Indicates the failure of a request to ARM7 that was issued using PXI communications.
RTC_RESULT_INVALID_COMMAND | Indicates that the request could not be performed because the request received by ARM7 was not a supported command.
RTC_RESULT_ILLEGAL_STATUS | Indicates that the request could not be performed because of RTC internal status. This error is not generated during normal application of the RTC library.
RTC_RESULT_FATAL_ERROR | Indicates that proper process was not possible due to a cause not listed above. This error is not generated during normal application of the RTC library.
