Nettetintptr_t. intptr_t is a signed integer memsize-type that can safely store a pointer regardless of the platform capacity. The type intptr_t is similar to the types ptrdiff_t and INT_PTR. The size of the type depends upon the data model. To learn more about memsize types and ways of using them see the article "About size_t and ptrdiff_t". In … Nettet(u)intptr_t is used when you want to do arithmetic on pointers, specifically bitwise operations. But as others said, you'll almost always want to use uintptr_t because bitwise operations are better done in unsigned. However if you need to do an arithmetic right shift then you must use intptr_t. mario coimbatore
