Description

This structure is used by RARReadHeader function.

Structure fields

• ArcName

  Output parameter which contains a zero terminated string of the current archive name. May be used to determine the current volume name.

• FileName

  Output parameter which contains a zero terminated string of the file name in OEM (DOS) encoding.

• Flags

  Output parameter which contains file flags:

  RHDF_SPLITBEFORE	0x01	File continued from previous volume
  RHDF_SPLITAFTER	0x02	File continued on next volume
  RHDF_ENCRYPTED	0x04	File encrypted with password
  	0x08	Reserved
  RHDF_SOLID	0x10	Previous files data is used (solid flag)
  RHDF_DIRECTORY	0x20	Directory entry

  Other bits are reserved.

• PackSize

  Output parameter. Packed file size or size of file part if file was split between volumes.

• UnpSize

  Output parameter. Unpacked file size.

• HostOS

  Output parameter. Operating system used to create the archive.

  0	MS DOS
  1	OS/2
  2	Windows
  3	Unix

• FileCRC

  Output parameter, which contains unpacked file CRC32. In case of file parts split between volumes only the last part contains the correct CRC and it is accessible only in RAR_OM_LIST_INCSPLIT listing mode.

• FileTime

  Output parameter. Contains the file modification date and time in standard MS DOS format.

• UnpVer

  Output parameter. RAR version needed to extract file. It is encoded as 10 * Major version + minor version.

• Method

  Output parameter. Packing method.

  0x30	Storing
  0x31	Fastest compression
  0x32	Fast compression
  0x33	Normal compression
  0x34	Good compression
  0x35	Best compression

• FileAttr

  Output parameter. File attributes.
