I have been trying to get some work done on a class returned by
CreateTextServices, but the differences between windows' stdcall and
linux' are giving me a few headaches. right now I've done it pretty much
like this:
/* These macros are taken from wine/dlls/msvcrt/cpp.c */
#ifdef __i386__ /* thiscall functions are i386-specific */
#define THISCALL(func) __thiscall_ ## func
#define THISCALL_NAME(func) __ASM_NAME("__thiscall_" #func)
#define DEFINE_THISCALL_WRAPPER(func) \
extern void THISCALL(func)(); \
__ASM_GLOBAL_FUNC(__thiscall_ ## func, \
"popl %eax\n\t" \
"pushl %ecx\n\t" \
"pushl %eax\n\t" \
"jmp " __ASM_NAME(#func) )
#else /* __i386__ */
#define THISCALL(func) func
#define THISCALL_NAME(func) __ASM_NAME(#func)
#define DEFINE_THISCALL_WRAPPER(func) /* nothing */
#endif /* __i386__ */
DEFINE_THISCALL_WRAPPER(fnTextSrv_TxSendMessage);
static HRESULT __stdcall fnTextSrv_TxSendMessage(ITextServices *iface,
UINT msg,
WPARAM wparam,
LPARAM lparam,
LRESULT* plresult)
{ .... }
static const ITextServicesVtbl textservices_Vtbl =
{
fnTextSrv_QueryInterface,
fnTextSrv_AddRef,
fnTextSrv_Release,
THISCALL(fnTextSrv_TxSendMessage),
... };
This works, however it is not clean, it gives me 2 compiler warnings:
1: fnTextServ_TxSendMessage defined but not used
2: initialisation from incompatible pointer type (in the vtable)
I wonder how I can do this cleaner (Meaning no compiler warnings without
ugly hacks). Also I would like to know how to call a function like
__thiscall_fnTextSrv_TxSendMessage, because some methods I need are
implemented in windows' stdcall. And I would like to know wether
include/textserv.h needs to be adjusted now that I know they are not WINAPI.
