[fpc-pascal] Sparse files and and copy-on-write filesystems

[Mark Morgan Lloyd]

Does FPC have any support these days for creating and accessing sparse 
files, in particular on Linux? I'm considering a file containing a 2Gb 
fixed-size filesystem, with one or more sparse files logging updates. 
Obviously I could use something like Qemu's qcow format, but initially 
at least I think I'd prefer to be able to use raw files.
