Rangers did edge shades of a scrappy affair and created a handful of half-chances, the most notable of which was debutant Ishmael Miller's disallowed effort for offside.
But it was Hull who had had the best opening and only Matt Fryatt's profligacy kept the affair goalless, although Warnock would have felt aggrieved to have lost out - and claimed only his men were chasing the three points.
"I'm disappointed and frustrated," said Warnock. "I think you've got to say you're happy when they have a clear chance like they had at the end.
"But, no, I'm really frustrated. I was surprised how Hull set the stall out - put the bus in front of the goal.
"I felt we dominated the game for 80 minutes. I just thought the last 10 minutes they had a little bit. We could have done a lot better in the last third. We didn't test the keeper enough."
