People,

I need some help from converting for converting a C API to a D module. I have some questions and dont now how solving that :

1 - This tranlation is correct ?


long __stdcall isc_attach_database (
   int  *,
   short,
   char *,
   isc_db_handle  *,
   short,
   char *
 );

To :

extern(C) {

int isc_attach_database(
	int *,
	short *,
	char *,
	isc_db_handle *,
	char *
)

}


2 - This tranlation is correct ?

long __cdecl isc_event_block (
   char * *,
   char * *,
   unsigned short,
   ...
   );

To :

extern(C) {

int isc_event_block(
   char * *,
   char * *,
   unsigned short,
   ...
   );
 }

 3 - in D long is 64 bits long ?


4 - This translation is correct ?

typedef struct isc_blob_ctl{
    long      (*ctl_source)();
    struct isc_blob_ctl *ctl_source_handle;
    short		  ctl_to_sub_type;
    short		  ctl_from_sub_type;

} *ISC_BLOB_CTL;

To :

struct isc_blob_ctl{
    int()		  ctl_source;
    isc_blob_ctl*	  ctl_source_handle;
    short		  ctl_to_sub_type;
    short		  ctl_from_sub_type;

};

isc_blob_ctl* ISC_BLOB_CTL;

5 - Is correct ?

typedef void     *isc_att_handle;

To :

typedef void*	 isc_att_handle;

6 - For compiling and liking what I need ?

a ) the module ibase.d
b) the ibase.lib
c ) the ibase.dll

How this 3 things have connection ?

Thanks

stdcall translates to extern (Windows)

unsigned short translates to ushort.

Yes.

No, int(*ctl_source)();

alias void* isc_att_handle;

It would be analogous to C. dlls are only necessary if you want to use them. They are not required like in java.

I marked two spots in your source
with an arrow:   // <-----
I think they are translated wrong.

Read Walters comment for other points.
Hope this helps.

Is some mistakes when translating.

I need some help again. I have some doubts :


1 - Array within a structure have the Zero Position ?

typedef struct paramvary {
    ISC_USHORT		vary_length;
    unsigned char	vary_string [10];
} PARAMVARY;

could be translated to :

struct PARAMVARY {
    ISC_USHORT		vary_length;
    ubyte[10]		vary_string;
};


2 - Far pointer are banished ?

The calling convetion is defined by following macros :

#if (defined(_MSC_VER) && defined(_WIN32)) || \
    (defined(__BORLANDC__) && (defined(__WIN32__) || defined(__OS2__)))
#define  ISC_FAR
#define  ISC_EXPORT	__stdcall
#define  ISC_EXPORT_VARARG	__cdecl
typedef           __int64  ISC_INT64;
typedef  unsigned __int64  ISC_UINT64;
#define  ISC_INT64_DEFINED
#else					/* Not Windows/NT */
#if (defined(__IBMC__) && defined(__OS2__))
#define  ISC_FAR
#define  ISC_EXPORT	_System
#define  ISC_EXPORT_VARARG	ISC_EXPORT
#else					/* not IBM C Set++ for OS/2 */
#if ( defined( _Windows) || defined( _WINDOWS))
#define  ISC_FAR	__far
#define  ISC_EXPORT     ISC_FAR __cdecl __loadds __export
#define  ISC_EXPORT_VARARG	ISC_EXPORT
#else					/* Not Windows/NT, OS/2 or Windows */
#define  ISC_FAR
#define  ISC_EXPORT
#define  ISC_EXPORT_VARARG
#endif					/* Windows and Not Windows/NT or OS/2
*/
#endif					/* IBM C Set++ for OS/2 */
#endif   				/* Windows/NT */


My conclusion is :

ISC_FAR	   : ''
ISC_EXPORT : '__stdcall'
ISC_EXPORT_VARARG : '__cdecl'

This is right ?

and then ->

typedef struct {

    short	sqllen;
    char  ISC_FAR *sqldata;
} XSQLVAR;

can be translated to :

struct XSQLVAR {

    short	sqllen;
    char*	sqldata;
};

What do you mean, "zero position"? Array in structure doesn't differ from any other array...

Yep, right.
Just remove that ; after the }

> 2 - Far pointer are banished ?

Since D is 32-bit and higher, there is no need in near/far pointers.

Yes.

In struct estrutura { char[5] array } , array has 5 bytes + the lenght of array?

Of course no. It's a static array, and thus stored in the same way as in C/C++. Only dynamic arrays store their length at run-time.
