MultiByteToWideChar are called directly only from one function. All other colls in comctl32 go thrue this function. It was recovered with from dissassambled code.

This is not allowed in Wine development. All you can use is tests, but after this patch you're most likely banned (from comctl32 changes at least).

Ouch... bad start. Hmm... but this code is present in wine-comctl32, it just spread in different parts.

We do not need to follow the original comctl32 bytewise.
You will find however functions called "head_strdupA2W" occasionaly
eg. dlls/wininet/internet.h:heap_strdupWtoA() and heap_strdupAtoW()
if you need to factor out such common tasks as string allocation + conversion.
Ciao, Marcus

Thank you for the tip, i'll do some clean job in comctl32, if i'm not banned :D

May be it make sense to place this function to winebase? Looks like there is some duplicates: dlls/mshtml/mshtml_private.h:static inline char *heap_strdupWtoA(LPCWSTR str) dlls/wininet/internet.h:static inline char *heap_strdupWtoA(LPCWSTR str) dlls/appwiz.cpl/addons.c:static inline char *heap_strdupWtoA(LPCWSTR str)

No, as it is not an officially exported API we cannot export it from public headers
