I am trying to figure out how to create an empty memmapfile object. My situation is this: I have a loop where I'm finding the files associated with a project and creating a memory map of each one. That memory map, along with various other information is returned in a structure, which becomes part of a structure array. I've had a problem where occasionally one of the files fails in the processing, and then the whole system comes crashing to a halt because I'm trying to map dissimilar types of structures into the structure array (because the new one doesn't have a valid memmapfile).
What I want to do is to be able to define a default structure that will be returned in the event of a failed file load, but then I need to include a memmapfile object in the returned structure. I don't want to try to memmap a meaningless file, because I suspect that Matlab would really not like it if I mapped the same dummy file multiple times. So what would be the equivalent of:
dummy = memmapfile(0) ?
Is it to use the metaclass(memmapfile)? I wouldn't think so, but I really don't understand metaclasses at all.
