fitsio without file access

[Martin Beckett]

I need to read and write fits files without necessarily having
a random access file, eg. to shared memory or Tcl i/o streams.
Idealy I would like the fits file to be created as just an
area in memory.

Unfortunately CFITSIO needs a real file.  I could create a 
temporary disk file and mmap() it back into memory but that
seems a bit daft.

Are there any other C/C++ fits libraries, or a patch to cfitsio
out there ?  Basically I'm too lazy to reinvent everything
