C++ (Cpp) generalTimeRegisterCurrentProvider Examples

Example #1

File: osiClockTime.c Project: ukaea/epics

static void ClockTime_InitOnce(void *pfirst)
{
    *(int *) pfirst = 1;

    ClockTimePvt.loopEvent   = epicsEventMustCreate(epicsEventEmpty);
    ClockTimePvt.lock        = epicsMutexCreate();

    epicsAtExit(ClockTime_Shutdown, NULL);

    /* Register the iocsh commands */
    iocshRegister(&ReportFuncDef, ReportCallFunc);
    iocshRegister(&ShutdownFuncDef, ShutdownCallFunc);

    /* Register as a time provider */
    generalTimeRegisterCurrentProvider("OS Clock", LAST_RESORT_PRIORITY,
        ClockTimeGetCurrent);
}

Example #2

File: osiNTPTime.c Project: A2-Collaboration/epics

static void NTPTime_InitOnce(void *pprio)
{
    struct timespec timespecNow;

    NTPTimePvt.synchronize    = 1;

    NTPTimePvt.lock           = epicsMutexCreate();

    /* Initialize OS-dependent code */

    /* Start the sync thread */
