Allocating memory for a windows structure

[HyperEngineer]

I am trying to allocate memory for a SP_DEVICE_INTERFACE_DATA structure.
In a Windows based program using VS2008 I successfully used this:

#include <windows.h>
#include <winbase.h>
 
...
 
   SP_DEVICE_INTERFACE_DATA deviceinterface;
   SecureZeroMemory(&deviceinterface, sizeof(SP_DEVICE_INTERFACE_DATA));
 
...

#include <windows.h>
#include <winbase.h>

...

   SP_DEVICE_INTERFACE_DATA deviceinterface;
   SecureZeroMemory(&deviceinterface, sizeof(SP_DEVICE_INTERFACE_DATA));

...

To copy to clipboard, switch view to plain text mode 

In QT 4 using netbeans 7.2.1 I am trying to use:

#include <windows.h>
#include <winbase.h>
 
...
 
   SP_DEVICE_INTERFACE_DATA devInterfaceInfo;
   devInterfaceInfo = 
     (SP_DEVICE_INTERFACE_DATA)malloc(sizeof(SP_DEVICE_INTERFACE_DATA));
 
...

#include <windows.h>
#include <winbase.h>

...

   SP_DEVICE_INTERFACE_DATA devInterfaceInfo;
   devInterfaceInfo = 
     (SP_DEVICE_INTERFACE_DATA)malloc(sizeof(SP_DEVICE_INTERFACE_DATA));

...

To copy to clipboard, switch view to plain text mode 

In QT 4 I get the following error:

QEnumerator.cpp:57: error: no matching function for call to '_SP_DEVICE_INTERFACE_DATA::_SP_DEVICE_INTERFACE_D ATA(void*)'
c:\qtsdk\mingw\bin\../lib/gcc/mingw32/4.4.0/../../../../include/setupapi.h:722: note: candidates are: _SP_DEVICE_INTERFACE_DATA::_SP_DEVICE_INTERFACE_DA TA()
c:\qtsdk\mingw\bin\../lib/gcc/mingw32/4.4.0/../../../../include/setupapi.h:722: note: _SP_DEVICE_INTERFACE_DATA::_SP_DEVICE_INTERFACE_DA TA(const _SP_DEVICE_INTERFACE_DATA&)

I have successfully used the malloc() function in QT 4 for other structures and devtypes.
Any help would be appreciated.

Thanks

This is not a Qt problem but the gcc problem. Qt is only C++ library.

Thanks, Lesiok. I will look elsewhere.
