string (C++)

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

Indicates that the one-dimensional char, wchar_t, byte (or equivalent) array or the pointer to such an array must be treated as a string.

  
[string]  
  

The string C++ attribute has the same functionality as the string MIDL attribute.

The following code shows how to use string on an interface and on a typedef:

// cpp_attr_ref_string.cpp  
// compile with: /LD  
#include "unknwn.h"  
[module(name="ATLFIRELib")];  
[export, string] typedef char a[21];  
[dispinterface, restricted, uuid("00000000-0000-0000-0000-000000000001")]  
__interface IFireTabCtrl  
{  
   [id(1)] HRESULT Method3([in, string] char *pC);  
};
