COM methods are supposed to use the stdcall calling convention, but the
native riched20 and the native headers just defines ITextHost and ITextServices to be a c++ class (i.e. using the thiscall calling convention). Just look at the native TextServ.h header.
Right, but for that you have the textHostVtbl with the THISCALL() wrapper.
The itextHostStdcallVtbl is just for the C COM macros used from Wine code as calling a thiscall function from Wine is a PITA. That is handled in editor.h: #ifdef __i386__ /* Use wrappers to perform thiscall on i386 */ #define TXTHOST_VTABLE(This) (&itextHostStdcallVtbl) #else /* __i386__ */ #define TXTHOST_VTABLE(This) (This)->lpVtbl #endif /* __i386__ */ /*** ITextHost methods ***/ #define ITextHost_TxGetDC(This) TXTHOST_VTABLE(This)->TxGetDC(This) #define ITextHost_TxReleaseDC(This,a) TXTHOST_VTABLE(This)->TxReleaseDC(This,a) ...
On i386 Wine is calling functions from the static itextHostStdcallVtbl and those functions are not thiscall. Of course I might miss something as that code is mind warping...
