Disk I/O for reading and/or writing data

If you want to read/write image data from/to disk use the STFGET (SCFGET) and STFPUT (SCFPUT) interfaces. Like with the mapping/unmapping interfaces the data are converted, if necessary.

You should not mix the two modes of accessing image data. That means, do not e.g. use STFMAP (SCFMAP) and STFGET (SCFGET) calls together for a frame.
