Scatter/Gather List Element
You use scatter/gather lists to specify the data buffers to be used for a transfer. A scatter/gather list consists of one or more elements, each of which describes the location and size of one buffer.
The scatter/gather list element is defined by the SGRecord data type.
struct SGRecord
{
   Ptr      SGAddr;
   SInt32   SGCount;
};
typedef struct SGRecord SGRecord;
Field Description
