string format for intptr_t and uintptr_t
Solution 1:
That would be the following macros from inttypes.h:
For printf:
PRIdPTR PRIiPTR PRIoPTR PRIuPTR PRIxPTR PRIXPTR
For scanf:
SCNdPTR SCNiPTR SCNoPTR SCNuPTR SCNxPTR
Usage example:
uintptr_t p = SOME_VALUE;
printf("Here's a pointer for you: %" PRIxPTR "\n", p);
Solution 2:
I think you should consider using the 'z' modifier. This will convert anything that corresponds to a size_t og ssize_t, and I have found that it works with (u)intptr_t as well.
For example:
intptr_t ip = ...; printf("ip = %zd\n", ip);
