GetWindowThreadProcessId
The GetWindowThreadProcessId
function retrieves the identifier of the thread that created the specified
window and, optionally, the identifier of the process that created the window.
This function supersedes the GetWindowTask function.
DWORD GetWindowThreadProcessId(
|
HWND hWnd, |
// handle of window |
|
LPDWORD lpdwProcessId |
// address of variable
for process identifier |
|
); |
|
Parameters
hWnd
Identifies
the window.
lpdwProcessId
Points to a
32-bit value that receives the process identifier. If this parameter is not
NULL, GetWindowThreadProcessId copies the identifier of the process to
the 32-bit value; otherwise, it does not.
Return Values
The return
value is the identifier of the thread that created the window.
Remarks
This function
replaces the GetWindowTask
function of Windows version 3.x.
