The most common operating systems (Windows, Linux, macOS) use the LP64 and LLP64 data models, where int is 32-bit. Putting a 64-bit pointer into a 32-bit variable causes the cutting of high-order bits, and therefore incorrect program behavior.

WebSep 8, 2011 · I wasn't complaining about the lack of a 64-Bit type or proposing that it should be implemented, just saying that the acceptance of the "long long" variable type by this compiler is misleading and that it should be removed (because the C standard says that a long long must be at least 64-Bit). WebAs shown in the link above - a long has 32 bits on some systems and 64 bits on others. A long long always has 64 bits. A size_t could be a unique type or could map an existing type according to the spec. It appears that in modern compilers it either maps to a long or a long long depending on system bit width and long definition.
