The WM_CAP_ABORT message stops the capture operation. In the case of step capture, the image data collected up to the point of the WM_CAP_ABORT message will be retained in the capture file, but audio will not be captured. You can send this message explicitly or by using the capCaptureAbort macro.
WM_CAP_ABORT
wParam = (WPARAM) 0;
lParam = 0L;
Returns TRUE if successful or FALSE otherwise.
The capture operation must yield to use this message.
Use the WM_CAP_STOP message to halt step capture at the current position, and then capture audio.
