[jira] Commented: (AXIS2C-919) primitive types - long vs. int64_t

Senaka Fernando commented on AXIS2C-919:
----------------------------------------

Hi Frank,

I believe that it can be added. Plus any other standard types, so that users can make use of these. However, the names of types may require to be changed according to axis2/c conventions. And, we'll have to consider using long vs. uint64_t at all occurrences, because the longer the type, the greater the overhead.

I believe it would be better if you could suggest exactly what location(s) do you want this replacement to be made. I don't think we need to be replacing all.

Regards,
Senaka

> I'm running into a problem with Axis2/C regarding the primitive types used in certain situations, especially when using Axis2/C cross platform and cross implementation. Specifically, I have several primitive types which are longs to represent values in excess of 2GB. This works fine on C# and Java (which we are using on our platforms). However, on C++ compiled on a WinXP 32-bit system, the long type is only 4 bytes long (as the int type) and thus not sufficient to represent large numbers.
> The way I have gotten around this problem while keeping cross-platform compatibility in mind are the following defines:
> #if defined(_WINDOWS)
> // Windows doesn't have any of the standard ANSI size invariant
> // Ansi types
> typedef unsigned __int8  uint8_t;
> typedef __int8            int8_t;
> typedef unsigned __int16 uint16_t;
> typedef __int16           int16_t;
> typedef unsigned __int32 uint32_t;
> typedef __int32           int32_t;
> typedef unsigned __int64 uint64_t;
> typedef __int64           int64_t;
> #else
> // Non Windows platforms should have this header file, which should
> // give access to the ansi types like uint8_t etc.
> #include <stdint.h>
> #endif // !_WINDOWS
> Is it possible to use these ansi types instead of types which will invariably truncate very large numbers, such as longs? I would consider this to be a very important improvement to the generated code.
> Any further comments are highly appreciated.
> Cheers,
> Frank
