Input Of an Unspecified Amount From a User

I am working on a project where the user enters in an unspecified amount of integers.  I havent came up with a good solution.

I can have the user enter the integers using scanf.  Scanf returns the amount of items entered I can use this to determine how much memory to allocate with malloc.  The problem is does scanf only count the valid data
(integers as opposed to characters?).  How would I handle if a character was in the mix of integers?


Am I headed in the right direction on this or does anyoen have a much better way of handling this.

Thanks
