newbie creating scatter/gather list

Hi all,

I want to create a scatter/gather list for dma from a pci device. I've read
DMA-mapping.txt and a host of other stuff, but most of it assumes I know
the 'basics' already, which I don't and can't find. Kernelnewbies sent me
here.

I want to use the pci_map_sg() function detailed in DMA-mapping .txt, but
have to pass an already created scatter list to it. Can anyone tell me how
to do it, or where to find details on it (an example program?).

Thanks, the help is needed and appreciated.

Oliver.
