Hi John

Just as an example

# include <stdio.h>
# include <time.h>
# pragma intrinsic XCONTRAP
# pragma intrinsic RESETCONTROL
void dotrap(void)
{
    int oldplabel;
    time_t Time;
    Time = time(NULL);
    printf("<control-y>...%s", ctime(&Time));
    XCONTRAP((int) dotrap, &oldplabel);
    RESETCONTROL();
}
int main(int argc, char *argv[])
{
    int oldplabel;
    XCONTRAP((int) dotrap, &oldplabel);
    sleep(60);
    XCONTRAP(0, &oldplabel);
}

Note that pressing control-y resets the sleep to
sixty seconds every time, better not mix
intrinsic and c library functions

HTH

Johan
