problem with real-time

hello every1,
i'm very hope so anyone here have experience with lib rt like aio linux based.
In first I've a problem with receiving data from aio_buf, i.e. I have received it, but if the next data size less then pervious I've got a noise from a socket. I've tried to fix it by different ways, but unfortunately still didn't.
And second...

Standard i\o doesn't work here, how I can write to socket handle so as to reply on received message?
char *buf;
// whatever
static const struct aiocb *list[5] = {&a_read,NULL,NULL,NULL,NULL};
ret = aio_read( &a_read );
while (aio_suspend( list, 5, NULL ) == 0){
	ret = aio_read( &a_read );
        write(sock, buf, 11);
