EnumThreadWindows

The EnumThreadWindows function enumerates all nonchild windows associated with a thread by passing the handle of each window, in turn, to an application-defined callback function. EnumThreadWindows continues until the last window is enumerated or the callback function returns FALSE. To enumerate child windows of a particular window, use the EnumChildWindows function. This function supersedes the EnumTaskWindows function.

BOOL EnumThreadWindows(

DWORD dwThreadId,	// thread identifier
WNDENUMPROC lpfn,	// pointer to callback function
LPARAM lParam	// application-defined value
);

Parameters

dwThreadId

Identifies the thread whose windows are to be enumerated.

lpfn

Points to an application-defined callback function. For more information about the callback function, see the EnumThreadWndProc callback function.

lParam

Specifies a 32-bit, application-defined value to be passed to the callback function.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.
