In this case I would advise not to free the pointer and explicitly document this choice in the freepascal documentation. (As the user can free the area himself anyways, but can not bring it back).
Yes, exactly.
Maybe it would help you more to allocate more space in advance? Or use a data structure not requiring reallocations ? Just some suggestions...
Your are right, it would be faster but this is not possible. For instance, suppose you are a user of the library and you want to compute !10000, i.e., Factorial 10000. Currently, all you have to do is to write "IFactorial(N,10000)". Now what if, before calling IFactorial, it is necessary to estimate the size of !10000 in order to oversize N? Yes, you lovely archive the library in the trush and you search for an other one :-)
