Castles were very hard to take and required several months of siege and a numerically superior force to take. It was really a logistical battle between the siege force and the castle. If the siege force ran out of food, which was common given the logistics of most armies at the time, it would have to withdraw and end the siege. If the attacker was smart they would only lay siege if they had adequate supplies and could fend off any counterattacks.

The Siege of ParisOrléans in which Joan of Arc fought was a good example of a castle/fortress which successfully outlasted the attackers until help could arrive.
