568 * Name : BOOL WIN32API OS2GetClassInfoExW
569 * Purpose : The GetClassInfoEx function retrieves information about a window
570 * class, including the handle of the small icon associated with the
571 * window class. GetClassInfo does not retrieve the handle of the small icon.
572 * Parameters: HINSTANCE hinst handle of application instance
573 * LPCWSTR lpszClass address of class name string
574 * LPWNDCLASSEX lpwcx address of structure for class data
575 * Variables :
576 * Result : If the function finds a matching class and successfully copies
577 * the data, the return value is TRUE;
578 * otherwise, it is FALSE.
579 * To get extended error information, call GetLastError.
580 * Remark : does not obtain handle of the small icon
