SGSetChannelMaxFrames

The SGSetChannelMaxFrames function allows the sequence grabber to limit the number of frames that your channel component will capture during a record operation.

pascal ComponentResult SGSetChannelMaxFrames (SGChannel c, 
                                              long frameCount);

c

Identifies the channel connection for this operation.

frameCount

Specifies the maximum number of frames to capture during the preview or record operation. The sequence grabber component sets this parameter to -1 to remove the limit.

DESCRIPTION

The SGSetChannelMaxFrames function works only with channels that have data that is organized into frames, such as video data from a video disc.

RESULT CODES

paramErr	-50	Invalid parameter specified
cantDoThatInCurrentMode	-9402	Request invalid in current mode

SEE ALSO

You report whether your channel's data is organized into frames in your response to the SGGetChannelInfo function, which is described on page 6-47.
