Is there any way of finding out the name of the file to which "hello"
has been written? I do know the file identifier (stored in fid), but
don't know the file name.
If you want the name, use tmpname() and fopen(), for instance like this:
fopen(fname=tmpnam(),'w')
By the way, on Linux you can tease out the name of a file by the file
descriptor number:
system(['ls -l /proc/$$/fd/' num2str(fid)])
