Try this:

------------------------------------
#include <sys/types.h>
#include <sys/time.h>

usleep(usecs)
        u_long usecs;
{
        struct timeval tv;

        tv.tv_sec = usecs / 1000000L;
        tv.tv_usec = usecs % 1000000L;
        (void)select(0, 0, 0, 0, &tv);
}

------------------------------------

By the way, this was not written by me, I just grabbed it from another HP
machine.
