#ifndef _MAP_H_

/* Place functions to handle a process open files here (file list).
flist.h : Your function declarations and documentation.
flist.c : Your implementation.
The following is strongly recommended:
- A function that given a file (struct file*, see filesys/file.h)
and a process id INSERT this in a list of files. Return an
integer that can be used to find the opened file later.
- A function that given an integer (obtained from above function)
and a process id FIND the file in a list. Should return NULL if
the specified process did not insert the file or already removed
it.
- A function that given an integer (obtained from above function)
and a process id REMOVE the file from a list. Should return NULL
if the specified process did not insert the file or already
removed it.
- A function that given a process id REMOVE ALL files the specified
process have in the list.
All files obtained from filesys/filesys.c:filesys_open() are
considered OPEN files and must be added to a list or else kept
track of, to guarantee ALL open files are eventyally CLOSED
(probably when removed from the list(s)).
