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

Return Values

If the function fails, the return value is zero.
