Article ID: 946924 - Last Review: February 29, 2008 - Revision: 1.1 When a 32-bit process calls the GetRawInputDeviceList function on a computer that is running a 64-bit version of Windows Vista or a 64-bit version of Windows Server 2003, memory corruption occurs
On This PageSYMPTOMSConsider the following scenario:
CAUSEThis problem occurs because the WOW64 layer incorrectly marshals the pointer that points to the RAWINPUTDEVICELIST array when the process calls the 64-bit GetRawInputDeviceList function. RESOLUTIONA hotfix is available to resolve this problem. However, this hotfix is limited to existing applications that call the GetRawInputDevice function from a 32-bit process that is running on a 64-bit version of Windows. New applications should call the GetRawInputDeviceList function according to the new Windows SDK documentation. Hotfix information for Windows VistaA supported hotfix is available from Microsoft.

STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. MORE INFORMATIONThe Windows SDK documentation incorrectly states that the puiNumDevices parameter contains the size, in bytes, of the preallocated buffer to which the pRawInputDeviceList parameter points. This documentation should state that the puiNumDevices parameter specifies the number of RAWINPUTDEVICELIST structures that can be contained in the buffer to which the pRawInputDeviceList parameter points.
