midl question

[Alistair Leslie-Hughes]

Hi,

In an IDL file I need to define the following
typedef HRESULT (__stdcall *FExecuteInAppDomainCallback) (void* cookie);

How do i get midl to understand what __stdcall is defined to?

Best Regards

indexsrv.idl does:

cpp_quote("struct tagTEXT_SOURCE;")
cpp_quote("typedef HRESULT (WINAPI *PFNFILLTEXTBUFFER)(struct tagTEXT_SOURCE *pTextSource);")

This isnt going to work for me.  Here is more information that I should of included in the first email.
interface ICLRRuntimeHost : IUnknown
...
HRESULT ExecuteInAppDomain([in] DWORD dwAppDomainId,                               [in] FExecuteInAppDomainCallback pCallback,                               [in] void* cookie);
...
So FExecuteInAppDomainCallback has to be defined or I will get compile errors.

midl or widl? AFAIK midl supports the __stdcall keyword.

Hi Rob,

What work would need to be done to get widl to support __stdcall?

The issue is that widl doesn't support functions in typedefs. Further 
issues are that widl doesn't support writing out the function typedef 
once parsed and widl doesn't store the calling convention for the 
function and so it currently can't be written out correctly.
