GlueGen Data Type Mapping

Gluegen has build-in types (terminal symbols) for:

type	java bits	native-x32 bits	native-x64 bits	type	signed	origin
void	0	0	0	void	void	ANSI-C
char	8	8	8	integer	signed or unsigned	ANSI-C
short	16	16	16	integer	signed or unsigned	ANSI-C
int	32	32	32	integer	signed or unsigned	ANSI-C
long	64	32	32¹	integer	signed or unsigned	Windows
long	64	32	64	integer	signed or unsigned	Unix
float	32	32	32	float	signed	ANSI-C
double	64	64	64	double	signed	ANSI-C
__int32	32	32	32	integer	signed or unsigned	windows
int32_t	32	32	32	integer	signed	stdint.h
wchar_t	32	32	32	integer	signed	stddef.h
uint32_t	32	32	32	integer	unsigned	stdint.h
__int64	64	64	64	integer	signed or unsigned	windows
int64_t	64	64	64	integer	signed	stdint.h
uint64_t	64	64	64	integer	unsigned	stdint.h
ptrdiff_t	64	32	64	integer	signed	stddef.h
intptr_t	64	32	64	integer	signed	stdint.h
size_t	64	32	64	integer	unsigned	stddef.h
uintptr_t	64	32	64	integer	unsigned	stdint.h

Warning: Try to avoid unspecified bit sized types, especially long, since it differs on Unix and Windows!
Note 1: Type long will result in broken code on Windows, since we don't differentiate the OS and it's bit size is ambiguous.

GlueGen Platform Header Files

GlueGen provides convenient platform headers,
which can be included in your C header files for native compilation and GlueGen code generation.

Example:

   #include <gluegen_stdint.h>
   #include <gluegen_stddef.h>
 
   uint64_t test64;
   size_t size1;
   ptrdiff_t ptr1;

To compile this file you have to include the following folder to your compilers system includes, ie -I:

    gluegen/make/stub_includes/platform

To generate code for this file you have to include the following folder to your GlueGen includeRefid element:

    gluegen/make/stub_includes/gluegen

GlueGen Pre-Defined Macros

To identity a GlueGen code generation run, GlueGen defines the following macros:

     #define __GLUEGEN__ 2
