Int data types (signed or unsigned) can be 16 or 32 bits depending on the platform. The
same way that long data types can be 32 or 64 bits depending on the platform. On most
machines that run GNU C Library, an int is a 32-bit quantity. On most machines, long
int is also 32-bit, the same size as int. And lastly, on most machines, long long int
are 64-bit quantities. View more at: https://www.gnu.org/software/libc/manual/html_node/Range-of-Type.html
As of 2024, 'h', 'i', 'l', and 'q' are usually 2, 4, 4 on Windows else 8, and 8 bytes.

This note talks about h, so if it's kept, the \(2) should be added to the h & H lines in the table.

But, maybe this PR should be closed without merging. If you're wrinting cross-platform code you shouldn't rely on “common” values; if not you can use itemsize to find values that are actually right for your platform.

Sorry, something went wrong.

IMHO "on most machines ..." doesn't really add anything.

In practice most general purpose machines are one of:

  • 32-bit CPUs: int, long are 32 bit, long long is 64 bit
  • 64-bit CPUs running Windows: int, long are 32-bit, long long is 64-bit
  • 64-bit CPUs running Unix-y systems (including Linux and macOS): int is 32-bit, long and long long are 64-bit

There are exceptions to this, but AFAIK most of those are special CPUs like DSPs or are from before the existence of C. Neither of which are useful to mention here.

Sorry, something went wrong.

The actual representation of values is determined by the machine architecture
