Sequence Grabber Component Functions / Controlling Sequence Grabber Components

SGRelease

The SGRelease function instructs the sequence grabber to release any system resources it allocated when you called the SGPrepare function, which is described in the previous section. You should call SGRelease whenever you call SGPrepare without subsequently starting a record or preview operation.

pascal ComponentResult SGRelease (SeqGrabComponent s);

s

Specifies the component instance that identifies your connection to the sequence grabber component. You obtain this value from the Component Manager's OpenDefaultComponent or OpenComponent function.

DESCRIPTION

When you stop a record or preview operation by calling the SGStop function, the sequence grabber component automatically releases the resources it uses during the operation. Consequently, you do not have to call this function after a record or
preview operation.

You cannot call the SGRelease function during a record or preview operation.
