Yes, correct and documented behaviour.


In regards to the comment on gna.org:

Removing an archive from the Search Path frees resources, closes 
physical files, etc. If we let you keep a handle to a file in a .zip, 
but close all our resources that reference that .zip, there would be 
problems. I don't think it's worth reference counting the archives, 
since this is just going to lead to memory leaks and poor design 
decisions at the application level.

For what it's worth, the proper Unix metaphor for 
PHYSFS_removeFromSearchPath() is not unlinking an inode, as the email 
you referenced suggests, but rather unmounting a filesystem. Indeed, in 
the development branch, PHYSFS_addToSearchPath(x,y) is shorthand for 
PHYSFS_mount(x, "/", y).

Naming the list of open archives the "search path" was probably the real 
design error here.

Feel free to forward this email, if you like.
