in thread 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); }
bot::add_idle_callback x7fc3ff9bc040 , x0 :: x7fc3ff9bc040 to x7fc3ff9bc040 :: to x7fc3ff9bc040 ::DPTR2FPTR x7fc3ff9bc040 to x7fc3ff9bc040 :: x0 to x0 :: to x0 ::DPTR2FPTR x0 to x0 ::in c add_idle_callback xff9bc040 , x0

    Tip:

    You can replace

    if(SvGMAGICAL($input)) mg_get($input);
    with
    SvGETMAGIC($input);

    (Just spotted that in a cursory glance. Didn't look at the rest.)
