Remarks

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

Example

The following code shows a use of wire_marshal:

// cpp_attr_ref_wire_marshal.cpp
// compile with: /LD
#include "windows.h"
[module(name="MyLibrary")];

[export, public] typedef unsigned long _FOUR_BYTE_DATA;

[export] typedef struct _TWO_X_TWO_BYTE_DATA {
   unsigned short low;
   unsigned short high;
} TWO_X_TWO_BYTE_DATA ;

[export, wire_marshal(TWO_X_TWO_BYTE_DATA)] typedef _FOUR_BYTE_DATA FOUR_BYTE_DATA;
