A default unsigned integer type for type T.
- The result is an unsigned integer type of the same width as T, if such an integer type exists. Otherwise, the type is
uintptr_t, an unsigned integer type that should be compatible with address arithmetic.
If T has the same width the result is
uintptr_t. Otherwise, the result type is chosen from
uint64_t. If none fits the width, we fall back on
As a consequence, if T is an integer type and the implementation has another integer type of the same width, this is not necessarily the integer type "corresponding" to T. E.g if T is
long long and has the same width as
long, the result type could well be
unsigned long instead of
unsigned long long.
