有没有办法与MIDL关闭C风格头生成？ [英] Is there a way with MIDL to turn off C-style headers generation?

问题描述

我有一个简单的.IDL文件（iface.idl），它描述了一个基于IUnknown的接口：

  importunknwn。 idl; 
 [
] [
 uuid（80DFDD28-F033-431e-B027-CDD2078FC78A）
] 
接口ISunPathCalc：IUnknown {
 HRESULT Square（[in，out] long * pVal ）; 
 HRESULT Cube（[in，out] long * pVal）; 
}; 
  

尝试使用 midl / header iface.h iface.idl 我得到3个文件：iface.h，iface_i.c和iface_p.c。 iface.h文件包含ISunpathCalc接口的C ++声明：

  #if defined（__ cplusplus）&& ！defined（CINTERFACE）
 
 MIDL_INTERFACE（80DFDD28-F033-431e-B027-CDD2078FC78A）
 ISunPathCalc：public IUnknown 
 {
 public：
 virtual HRESULT STDMETHODCALLTYPE Square（
 / * [out] [in] * / long * pVal）= 0; 
 
 virtual HRESULT STDMETHODCALLTYPE Cube（
 / * [out] [in] * / long * pVal）= 0; 
 
}; 
 
 #else / * C style interface * / 
  

有没有办法告诉MIDL只生成标头的C ++部分？
是否可以关闭iface_i.c和iface_p.c文件的生成，并强制MIDL生成一个C ++定义？

UPD1 ：

我尝试添加指定的[local]属性此处：

  [ 
 local，
 uuid（80DFDD28-F033-431e-B027-CDD2078FC78A）
] 
  

不幸的是，没有办法抑制C头生成。

I have a simple .IDL file (iface.idl) which describes an IUnknown based interface:

import "unknwn.idl"; 
[
    uuid(80DFDD28-F033-431e-B027-CDD2078FC78A)
]
interface ISunPathCalc : IUnknown {
    HRESULT Square([in, out] long * pVal);
    HRESULT Cube([in, out] long * pVal);
};

When trying to compile it with midl /header iface.h iface.idl I'm getting 3 files: iface.h, iface_i.c and iface_p.c. The iface.h file contains a C++ declaration of ISunpathCalc interface:

#if defined(__cplusplus) && !defined(CINTERFACE)

    MIDL_INTERFACE("80DFDD28-F033-431e-B027-CDD2078FC78A")
    ISunPathCalc : public IUnknown
    {
    public:
        virtual HRESULT STDMETHODCALLTYPE Square( 
            /* [out][in] */ long *pVal) = 0;

        virtual HRESULT STDMETHODCALLTYPE Cube( 
            /* [out][in] */ long *pVal) = 0;

    };

#else   /* C style interface */

The remaining larger part of this file contains needless C stuff.

Q: Is there way to tell MIDL to generate only C++ part of header? Is it possible to switch off generation of iface_i.c and iface_p.c files and to force MIDL to generate a C++ definition instead?

UPD1:

I tried to add [local] attribute as specified here:

[
    local,
    uuid(80DFDD28-F033-431e-B027-CDD2078FC78A)
]

but without any success.

解决方案

Unfortunately there's no way of suppressing the C header generation.
