function enumerates the child windows that belong to the specified parent
window by passing the handle of each child window, in turn, to an
application-defined callback function. EnumChildWindows
continues until the last child window is enumerated or the callback function
| HWND hWndParent,
||// handle to parent window
| WNDENUMPROC lpEnumFunc,
||// pointer to callback function
| LPARAM lParam
||// application-defined value
Identifies the parent window whose child windows are to be enumerated.
Points to an application-defined callback function. For more information about
the callback function, see the EnumChildProc
Specifies a 32-bit, application-defined value to be passed to the callback
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
function does not enumerate top-level windows owned by the specified window,
nor does it enumerate any other owned windows.
If a child window has created child windows of its own, this function
enumerates those windows as well.
A child window that is moved or repositioned in the Z order during the
enumeration process will be properly enumerated. The function does not enumerate a
child window that is destroyed before being enumerated or that is created during
the enumeration process.
This function is more reliable than calling the GetWindow
function in a loop. An application that calls GetWindow
to perform this task risks being caught in an infinite loop or referencing a
handle to a window that has been destroyed.
