SGGetChannelMaxFrames

The SGGetChannelMaxFrames function allows the sequence grabber component to determine the number of frames left to be captured from your channel.

pascal ComponentResult SGGetChannelMaxFrames (SGChannel c, 
                                              long *frameCount);

c

Identifies the channel connection for this operation.

frameCount

Contains a pointer to a long integer that is to receive a value specifying the number of frames left to be captured during the preview or record operation. If the returned value is -1, the sequence grabber channel component captures as many frames as it can.
