njb_datafile_struct Struct Reference

#include <libnjb.h>


Data Fields

char * filename
char * folder
u_int32_t timestamp
u_int32_t flags
u_int32_t dfid
u_int64_t filesize
njb_datafile_t * nextdf

Detailed Description

This is the struct storing the metadata of a regular file or folder.
Examples:

files.c, and getfile.c.

Field Documentation

u_int32_t njb_datafile_struct::dfid
 

The 32-bit unsigned file ID.

Examples:
files.c, and getfile.c.

char* njb_datafile_struct::filename
 

The name of this file. The name "." means that this is an empty folder name marker.

Examples:
files.c.

u_int64_t njb_datafile_struct::filesize
 

The file size as a 64-bit unsigned integer. The files on series 3 devices only have 32-bit signed length (and can only be 2GB in size) but the NJB1 supports 64-bit length.

Examples:
files.c, and getfile.c.

u_int32_t njb_datafile_struct::flags
 

These are ordinary windows file flags: 

 bit (from MSB)   meaning
 -----------------------------
 31               Normal file (0x80000000U)
 29               This file should be archived (0x20000000U) 
 28               Directory (0x10000000U)
 26               System file (0x04000000U)
 25               Hidden file (0x02000000U)
 24               Read only file (0x01000000U)
 22               Encrypted file (0x00400000U)
 21               Normal file? (0x00200000U)
 19               Compressed file (0x00080000U)
 17               Sparse file (0x00020000U)
 16               Temporary file (0x00010000U)

SAMBA maps the bits to Unix permissions thus:

  owner        group        world
  r  w  x      r  w  x      r  w  x
  ^  ^  ^            ^            ^
  |  |  |            |            |
  |  |  Archive      System       Hidden
  |  |
  Read only

The meaning of bits 30, 27, 23, 20 and 15-0 is unknown.

Examples:
files.c.

char* njb_datafile_struct::folder
 

This is the name of the folder the file belongs in. All folder names are given with full hierarchy and leading and trailing backslash as in: "\foo\bar\fnord\". If filename is "." this is the name of the empty folder.

Examples:
files.c.

njb_datafile_t* njb_datafile_struct::nextdf
 

This is only to be used internally by libnjb.

u_int32_t njb_datafile_struct::timestamp
 

This is an ordinary UNIX styled timestamp for the file.
