Identifies the channel connection for this operation.

frameRate

Contains a pointer to a field to receive the current frame rate. Return your channel's current frame rate.

DESCRIPTION

The SGGetFrameRate function returns your channel's current rate. By default, your channel should record at the fastest rate that it can support. In this case, set the field referred to by the frameRate parameter to 0.

The sequence grabber can set your channel's frame rate by calling the SGSetFrameRate function, which is described in the previous section.
