6     File operations
7     ---------------
8    
9     The file operations are also wrapped through file_open() and file_close()
10     which handle calling fd_open() / fd_close() and tracking the filedescriptors
11     correctly. fbopen() / fbclose() use file_open() / file_close() too.
12    
13     fileio.c defines the functions:
14    
15     int
16     file_open(const char *filename, int mode, int fmode)
17    
18     A wrapper around open(filename, flags, mode). Read the open manpage for
19     information. file_open() enforces filedescriptor limits and tags the FD
20     through fd_open().
21    
22     void
23     file_close(int fd)
24    
25     A wrapper around close() for files. close() handles fd_close()ing the fd.
26    
27    
28     FBFILE *
29     fbopen(const char *filename, const char *mode)
30    
31     void
32     fbclose(FBFILE *fb)
33    
34     These are the 'buffered disk IO' routines. You can read the code yourself.
35     Note that these routines use file_open() and file_close().
