Examples

There is no import library available that defines this function, so it is necessary to obtain a pointer to this function using LoadLibrary and GetProcAddress. The following example demonstrates how to obtain a pointer to this function.

Note

Using LoadLibrary incorrectly can compromise the security of your application by loading the wrong DLL. Refer to Dynamic-Link Library Search Order for information on how to correctly load DLLs with different versions of Microsoft Windows.

typedef HRESULT (WINAPI *PTF_ SAVESYSTEMACCTINPUTSETTINGS)(HWND hwndParent, HKEY hSourceRegKey);

HMODULE hInputDLL = LoadLibrary(TEXT("input.dll"));
BOOL bRet = FALSE;

if(hInputDLL == NULL)
{
    // Error loading module; fail as securely as possible. 
}
else
{
    PTF_ SAVESYSTEMACCTINPUTSETTINGS pfnSaveSystemAcctInputSettings;
    
    pfnSaveSystemAcctInputSettings = (PTF_ SAVESYSTEMACCTINPUTSETTINGS)GetProcAddress(hInputDLL, "SaveSystemAcctInputSettings ");

    if(pfnSaveSystemAcctInputSettings)
    {
        bRet = (*pfnSaveSystemAcctInputSettings)( hwndParent, hSourceRegKey);
    }

    FreeLibrary(hInputDLL);
}
