Difference between C-Types int32_t int_least32_t etc
c, stdint, types
Solution
`int32_t` is signed integer type with width of exactly 32 bits with no padding bits and using 2's complement for negative values. `int_least32_t` is smallest signed integer type with width of at least 32 bits. These are provided only if the implementation directly supports the type.
The typedefs that you are seeing simply means that in your environment both these requirements are satisfied by the standard `int` type itself. This need not mean that these typedefs are the same on a different environment.
Problem
I have ever read that int32_t is exact 32 bits long and int_least32_t only at least 32 bits, but they have both the same typedefs in my stdint.h: ``` typedef int int_least32_t; ``` and ``` typedef int int32_t; ``` So where is the difference? They exactly the same...
