[netCDF #VWI-224442]: Extending cxx or cxx4 to work from memory

Howdy Tom!

One feature we hope to add soon is support for diskless files, that is, files 
that exist only in memory. You can follow my progress on this issue here:
https://www.unidata.ucar.edu/jira/browse/NCF-5

Until that's done, my advice is to use temporary files, but store them on a RAM 
disk.

Good luck,

Ed
