More C Help needed

[Neil J Hosgood]

Hi All, I am converting a C header for CDBFAPI and getting a little stuck,
I have converted the FILTERVAR struct but am confused about the defines
below it.
Also how best to declare this in a UDT
should it be ASCIIZ or STRPTR ?

char  *normal_case;

and
struct DBF*    __stdcall  OpenBase  (char *filename);       //open database     
DECLARE FUCNTION OpenBase(FileName as ASCIIZ) as DBF PTR   ??

Any help appreciated.

'struct FilterVar {
'        char    v[1024];          //result STRING
'        char    c[1024];          //temporary simple condition
'        INT     t[1024];          //offset's of |&
'        INT     vr;               //offset IN result STRING
'        char    LEFT[1024];       //LEFT operand
'        char    RIGHT[1024];      //RIGHT operand
'        };
TYPE FilterVar
  v            AS STRING * 1024
  c            AS STRING * 1024
  t(1024)      AS LONG
  vr           AS LONG
  sleft        AS STRING * 1024
  sright       AS STRING * 1024
END TYPE

#define flt_c           d->filvar->c
#define flt_v           d->filvar->v
#define flt_t           d->filvar->t
#define flt_vr          d->filvar->vr
#define flt_left        d->filvar->LEFT
#define flt_right       d->filvar->RIGHT

DECLARE FUCNTION OpenBase LIB "cdbfapi.dll" ALIAS "OpenBase" (FileName as ASCIIZ) AS DWORD

TYPE FilterVar
  v            AS ASCIIZ * 1024
  c            AS ASCIIZ * 1024
  t(1023)      AS LONG   ' 0 TO 1023
  vr           AS LONG
  sleft        AS ASCIIZ * 1024
  sright       AS ASCIIZ * 1024
END TYPE

You don't need to translate the defines. They are simple shortcuts to access the members of the structure.

Great, thanks for that.

One more thing......

char *filename_bak; //NAME OF .bak file

is this a byte, pointer or asciiz ??


cheers,

Neil.

Asciiz Ptr.
