Description

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
