[Win32utils-devel] win32-api idea - wide method first based on $KCODE

[Berger, Daniel]

All,

Currently, the Win32::API.new method will search for the function name,
then the 'A' (ANSI) name, and finally the 'W' (Wide) name. The code
looks something like this:

fProc = GetProcAddress(hLibrary, TEXT(RSTRING(v_proc)->ptr));

if(!fProc){
   VALUE v_ascii = rb_str_new3(v_proc);
   v_ascii = rb_str_cat(v_ascii, "A", 1);
   fProc = GetProcAddress(hLibrary, TEXT(RSTRING(v_ascii)->ptr));

   if(!fProc){
      VALUE v_unicode = rb_str_new3(v_proc);
      v_unicode = rb_str_cat(v_unicode, "W", 1);
      fProc = GetProcAddress(hLibrary, TEXT(RSTRING(v_unicode)->ptr));
...

So, for example, when you do this:

Win32::API.new('SomeFunc',...)

It looks for SomeFunc. If that fails it looks for SomeFuncA (which is
what most of the functions actually default to). If that fails it looks
for SomeFuncW. If that fails, then an error is raised.

What about switching the order so that it looks for SomeFuncW -first-
and SomeFuncA -second- if $KCODE = u? Does that seem reasonable?

Dan
