What should be the sizeof(int) on a 64-bit machine?

Webbint is 32 bit, -2,147,483,648 to 2,147,483,647. Enough for almost 25 days worth of milliseconds (or almost 50 days if unsigned) long is 64 bit (-9223372036854775808 to 9223372036854775807). I don't know the performance impact of 64 bit operations on the ESP32, but that'd give you almost 300 million years worth of millisecond ticks. WebbThe data type sizes are partly what the compiler uses. But it is clearly advantageous to (1) use types that the machine supports efficiently and (2) use types consistently from the low-level libraries through user applications. Having to handle several variants is just a mess.
