Well this one I can answer. A simple milli-second sleep routine:
#include <sys/select.h>
#include <sys/time.h>
#include <sys/types.h>
#include <unistd.h>
static void
sleep_ms ( int milli )
{
struct timeval timeout;
/* Crude safety */
if ( milli <= 0 )
milli = 1;
timeout.tv_sec = milli / 1000;
timeout.tv_usec = ( milli % 1000 ) * 1000;
select ( 0, NULL, NULL, NULL, &timeout );
}
