One way is with clock_gettime() from the librt realtime library (link
with -l rt)
#include <stdio.h>
#include <time.h>
int main()
{
struct timespec ts;
if (clock_gettime(CLOCK_REALTIME, &ts) != 0) {perror("gettime
error:"); } else { printf("%ld %ld\n", ts.tv_sec, ts.tv_nsec); };
}

What happens now with your Lotus Notes apps - do you make another costly
upgrade, or settle for being marooned without product support? Time to move
off Lotus Notes and onto the cloud with Force.com, apps are easier to build,
use, and manage than apps on traditional platforms. Sign up for the Lotus
Notes Migration Kit to learn more. http://p.sf.net/sfu/salesforce-d2d
