Functions / Controlling Sequence Grabber Channel Components

SGStop

The SGStop function stops a preview or record operation.

pascal ComponentResult SGStop (SeqGrabComponent s);

s

Identifies the sequence grabber component that has connected to your channel component.

DESCRIPTION

In the case of a record operation, the sequence grabber component stores the collected movie data in the assigned movie file. The sequence grabber component then calls your SGWriteSamples function (described in the next section) to place the references to the captured data into the movie after it calls SGStop.

WARNING

It is dangerous to allow an update event to occur during recording. Many digitizers capture directly to the screen, and an update event will result in data loss.
