EnumWindowsProc
The EnumWindowsProc
function is an application-defined callback function that receives top-level
window handles as a result of a call to the EnumWindows or EnumDesktopWindows function.
BOOL CALLBACK EnumWindowsProc(
|
HWND hwnd, |
// handle to parent
window |
|
LPARAM lParam |
//
application-defined value |
|
); |
|
Parameters
hwnd
Identifies a
top-level window.
lParam
Specifies the
application-defined value given in EnumWindows or EnumDesktopWindows.
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 EnumWindows
or EnumDesktopWindows. EnumWindowsProc is a placeholder for the
application-defined function name. The WNDENUMPROC type is a pointer to
an EnumWindowsProc function.
