-File operations
----------------
-
-The file operations are also wrapped through file_open() and file_close()
-which handle calling fd_open() / fd_close() and tracking the filedescriptors
-correctly. fbopen() / fbclose() use file_open() / file_close() too.
-
-fileio.c defines the functions:
-
-int
-file_open(const char *filename, int mode, int fmode)
-
-A wrapper around open(filename, flags, mode). Read the open manpage for
-information. file_open() enforces filedescriptor limits and tags the FD
-through fd_open().
-
-void
-file_close(int fd)
-
-A wrapper around close() for files. close() handles fd_close()ing the fd.
-
-
-FBFILE *
-fbopen(const char *filename, const char *mode)
-
-void
-fbclose(FBFILE *fb)
-
-These are the 'buffered disk IO' routines. You can read the code yourself.
-Note that these routines use file_open() and file_close().
