Re^3: why SvUV() would crop to 32 bits?

yes thanks...spot on. the macro woz working all the way, but just the format cropping let me down. (although I must have missed it with gdb.)

so...

  printf(":: x%" UVxf " to ...", SvUV($input), $1);

does the job.

and here with a code example showing a few ugly ways to cast back pointers to all sorts...:

%typemap(in) void (* cb)(void *) , void *data , void (cb)(void *){
  //if SvGETMAGIC($input) {}; 
  $1 = INT2PTR($1_ltype, SvUV($input));
  printf(":: x%" UVxf " to x%lx\n", SvUV($input), $1);

  {
    int ret = SWIG_ConvertFunctionPtr($input, (void**)(& $1), 0);
    printf(":: to x%lx\n", $1);
  }

  if(SvGMAGICAL($input)) mg_get($input);
  $1 =  DPTR2FPTR($1_ltype, SvUV($input));
  printf("::DPTR2FPTR x%lx to x%lx\n", SvIV($input), $1);
}

Tip: You can replace `if(SvGMAGICAL($input)) mg_get($input);` [download] with `SvGETMAGIC($input);` [download] (Just spotted that in a cursory glance. Didn't look at the rest.)	[reply] [d/l] [select]
