The GetClassName function retrieves the class name of a window.
hwnd
Identifies the window.
lpszClassName
Points to a buffer that receives the null-terminated class name string.
cchClassName
Specifies the length of the buffer pointed to by the lpszClassName parameter. The class name string is truncated if it is longer than the buffer.
The return value is the length, in bytes, of the returned class name, not including the terminating null character. The return value is zero if the specified window handle is invalid.
