The minimum size for unsigned long is 4 bytes

  Oh I didn't realize its size varies on x86 and x64... I thought it's always 64-bit under compilers that target Linux! Today I learned...

    I think the size can vary by compiler rather than just by architecture.
    • dataflow 5y ago
      Yeah it can but in practice systems have a canonical model in their official headers.

        And yet msvc and gcc disagree on sizeof(long) on AMD64. Edit: but of course you meant OS with system, not hardware architecture :)
        • dataflow 5y ago
          MSVC on... Linux AMD64?
          • gpderetta 5y ago
            :) to be fair I did note my misunderstanding in my edit.

    There is a difference between 'long' and 'long long'. I believe the latter is always 64 bits on Linux.

      I'm indeed aware of that one :-)
