To follow current win32lib notation, use this:

constant
NOTIFYICONDATA_cbSize                   = allot( DWord ),
NOTIFYICONDATA_hWnd                     = allot( HndlAddr ),
NOTIFYICONDATA_uID                      = allot( Long ),
NOTIFYICONDATA_uFlags                   = allot( Long ),
NOTIFYICONDATA_uCallbackMessage = allot( Long ),
NOTIFYICONDATA_hIcon                    = allot( HndlAddr ),
NOTIFYICONDATA_szTip                    = allot( {64, Strz} ),
SIZEOF_NOTIFYICONDATA                   = allotted_size()

function struct_NOTIFYICONDATA( atom hWnd, atom uID, atom uFlags,
                atom uCallbackMessage, atom hIcon, sequence szTip )
        atom nid
        nid = acquire_mem(0, SIZEOF_NOTIFYICONDATA )
        store( nid, NOTIFYICONDATA_cbSize, SIZEOF_NOTIFYICONDATA )
        store( nid, NOTIFYICONDATA_hWnd, hWnd )
        store( nid, NOTIFYICONDATA_uID, uID )
        store( nid, NOTIFYICONDATA_uFlags )
        store( nid, NOTIFYICONDATA_uCallbackMessage )
        store( nid, NOTIFYICONDATA_hIcon, hIcon )
        store( nid, NOTIFYICONDATA_szTip, szTip )

        return nid
end function

To initialize and use the struct:

atom struct, mset

struct = struct_NOTIFYICONDATA( hWnd, uID, uFlags, uCallbackMessage, hIcon,
szTip )
mset = new_memset()
manage_mem( mset, struct )
..do stuff
release_mem( mset )

It looks like there are two parameters for FlashWindow.  Here's how you
should register the function:
--BOOL FlashWindow(
--    HWND  hWnd,       // handle of window to flash
--    BOOL  bInvert     // flash status
--   );

constant FlashWindow = registerw32Func( user32, "FlashWindow", { C_LONG,
C_SHORT }, C_SHORT )

So to call, you need to supply the handle of the window, and the flash
status:
Parameters

hWnd

Identifies the window to be flashed. The window can be either open or
minimized (iconic).

bInvert

Specifies whether the window is to be flashed or returned to its original
state. The window is flashed from one state to the other if this parameter
is TRUE. If it is FALSE, the window is returned to its original state
(either active or inactive).
Windows NT: If the window is iconic, this parameter is ignored.
Windows 95: When an application is iconic, the fInvert parameter is not
ignored. If this parameter is TRUE, the taskbar icon window flashes
active/inactive.
