How to Declare a 32-bit Integer in C

Question

What\'s the best way to declare an integer type which is always 4 byte on any platforms? I don\'t worry about certain device or old machines which has 16-bit int

Answer 1

stdint.h is the obvious choice, but it's not necessarily available.

If you're using a portable library, it's possible that it already provides portable fixed-width integers. For example, SDL has Sint32 (S is for “signed”), and GLib has gint32.
