Handling the Clock

The two functions described previously return K_OK if successful and K_EFAULT if the data is outside the actor's address space. The following code example illustrates the use of these two general functions:

Example 12-1 Handling the Clock

#include <stdio.h>
#include <stdlib.h>
#include <chorus.h>
int main( )
{
    KnTimeVal time;
    int result;
    result = sysTime(&time);
    if (result != K_OK) {
        fprintf(stderr, "error on sysTime %s\n", strSysError(result));
        exit(1);
    }
    printf("system time: %d seconds and %d nanoseconds\n",
					time.tmSec, time.tmNSec);
    result = 	sysTimeGetRes(&time);
    if (result != K_OK) {
        fprintf(stderr, "error on sysTime %s\n", strSysError(result));
        exit(1);
    }
    printf("time resolution: %d seconds and %d nanoseconds\n",
					time.tmSec, time.tmNSec);
}

This program produces the following output:

neon time1_u
started aid = 23
system time: 12013 seconds and 240000000 nanoseconds
time resolution: 0 seconds et 10000000 nanoseconds
