Do you mean something like std.mmfile.MmFile which operates on a file as an 
array in memory using mmap, or do you mean operating on memory that has no 
connection to a file at all (in which case, I'm not sure why you'd want to use 
File)? If the former, well use std.file.MmFile. If the latter, I expect that 
you're out of luck. Unfortunately, std.stdio.File is currently just a wrapper 
around FILE and is thus limited by what you can do with FILE - that and I 
don't think that the File API took into consideration the possibility of 
operating on anything other than an actual file (and I honestly don't know what 
you'd be trying to do with it where it would make any sense for to operate on 
anything other than an actual file).
