WebOct 20, 2016 · The warning is triggered only for size_t -- even though it is "just" a typedef for unsigned __int64, if you use uint64 directly, the warning isn't triggered as far as I can tell. But uint64_t didn't change size when you moved to 64 bits, and size_t did. WebThe names of the integer types and their sizes in each of the two data models are shown in the following table. Integers are always represented in twos-complement form in the native byte-encoding order of your system.
