WNDENUMPROC

The EnumThreadWndProc function is an application-defined callback function that receives the window handles associated with a thread as a result of a call to the EnumThreadWindows function.

BOOL CALLBACK EnumThreadWndProc(

HWND hwnd,	// handle to window
LPARAM lParam	// application-defined value
);

Parameters
hwnd

Identifies a window associated with the thread specified in the EnumThreadWindows function.

lParam

Specifies the application-defined value given in the EnumThreadWindows function.

Return Values
To continue enumeration, the callback function must return TRUE; to stop enumeration, it must return FALSE.

Remarks
The callback function can perform any desired task.

An application must register this callback function by passing its address to the EnumThreadWindows function. EnumThreadWndProc is a placeholder for the application-defined function name.
