This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer. Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer. Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk! Enjoy!

UnRAR.dll Manual
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
UnRAR.dll is a 32-bit Windows dynamic-link library which provides
|
|
file extraction from RAR archives.

|
|
Exported functions

====================================================================
|
|
HANDLE PASCAL RAROpenArchive(struct RAROpenArchiveData *ArchiveData)
|
|
====================================================================
|
|
|
|
Description
|
|
~~~~~~~~~~~
|
|
Open RAR archive and allocate memory structures
|
|
|
|
Parameters
|
|
~~~~~~~~~~
|
|
ArchiveData Points to RAROpenArchiveData structure
|
|
|
|
struct RAROpenArchiveData
|
|
{
|
|
char *ArcName;
|
|
UINT OpenMode;
|
|
UINT OpenResult;
|
|
char *CmtBuf;
|
|
UINT CmtBufSize;
|
|
UINT CmtSize;
|
|
UINT CmtState;
|
|
};
|
|
|
|
Structure fields:
|
|
|
|
ArcName
|
|
Input parameter which should point to zero terminated string
|
|
containing the archive name.
|
|
|
|
OpenMode
|
|
Input parameter.
|
|
|
|
Possible values
|
|
|
|
RAR_OM_LIST
|
|
Open archive for reading file headers only.
|
|
|
|
RAR_OM_EXTRACT
|
|
Open archive for testing and extracting files.
|
|
|
|
RAR_OM_LIST_INCSPLIT
|
|
Open archive for reading file headers only. If you open an archive
|
|
in such mode, RARReadHeader[Ex] will return all file headers,
|
|
including those with "file continued from previous volume" flag.
|
|
In case of RAR_OM_LIST such headers are automatically skipped.
|
|
So if you process RAR volumes in RAR_OM_LIST_INCSPLIT mode, you will
|
|
get several file header records for same file if file is split between
|
|
volumes. For such files only the last file header record will contain
|
|
the correct file CRC and if you wish to get the correct packed size,
|
|
you need to sum up packed sizes of all parts.
|
|
|
|
OpenResult
|
|
Output parameter.
|
|
|
|
Possible values
|
|
|
|
0 Success
|
|
ERAR_NO_MEMORY Not enough memory to initialize data structures
|
|
ERAR_BAD_DATA Archive header broken
|
|
ERAR_BAD_ARCHIVE File is not valid RAR archive
|
|
ERAR_UNKNOWN_FORMAT Unknown encryption used for archive headers
|
|
ERAR_EOPEN File open error
|
|
|
|
CmtBuf
|
|
Input parameter which should point to the buffer for archive
|
|
comments. Maximum comment size is limited to 64Kb. Comment text is
|
|
zero terminated. If the comment text is larger than the buffer
|
|
size, the comment text will be truncated. If CmtBuf is set to
|
|
NULL, comments will not be read.
|
|
|
|
CmtBufSize
|
|
Input parameter which should contain size of buffer for archive
|
|
comments.
|
|
|
|
CmtSize
|
|
Output parameter containing size of comments actually read into the
|
|
buffer, cannot exceed CmtBufSize.
|
|
|
|
CmtState
|
|
Output parameter.
|
|
|
|
Possible values
|
|
|
|
0 comments not present

====================================================================
|
|
|
|
Description
|
|
~~~~~~~~~~~
|
|
Performs action and moves the current position in the archive to
|
|
the next file. Extract or test the current file from the archive
|
|
opened in RAR_OM_EXTRACT mode. If the mode RAR_OM_LIST is set,
|
|
then a call to this function will simply skip the archive position
|
|
to the next file.
|
|
|
|
Parameters
|
|
~~~~~~~~~~
|
|
hArcData
|
|
This parameter should contain the archive handle obtained from the
|
|
RAROpenArchive function call.
|
|
|
|
Operation
|
|
File operation.
|
|
|
|
Possible values
|
|
|
|
RAR_SKIP Move to the next file in the archive. If the
|
|
archive is solid and RAR_OM_EXTRACT mode was set
|
|
when the archive was opened, the current file will
|
|
be processed - the operation will be performed
|
|
slower than a simple seek.
|
|
|
|
RAR_TEST Test the current file and move to the next file in
|
|
the archive. If the archive was opened with
|
|
RAR_OM_LIST mode, the operation is equal to
|
|
RAR_SKIP.
|
|
|
|
RAR_EXTRACT Extract the current file and move to the next file.
|
|
If the archive was opened with RAR_OM_LIST mode,
|
|
the operation is equal to RAR_SKIP.
|
|
|
|
|
|
DestPath
|
|
This parameter should point to a zero terminated string containing the
|
|
destination directory to which to extract files to. If DestPath is equal
|
|
to NULL, it means extract to the current directory. This parameter has
|
|
meaning only if DestName is NULL.
|
|
|
|
DestName
|
|
This parameter should point to a string containing the full path and name
|
|
to assign to extracted file or it can be NULL to use the default name.
|
|
If DestName is defined (not NULL), it overrides both the original file
|
|
name saved in the archive and path specigied in DestPath setting.
|
|
|
|
Both DestPath and DestName must be in OEM encoding. If necessary,
|
|
use CharToOem to convert text to OEM before passing to this function.
|
|
|
|
Return values
|
|
~~~~~~~~~~~~~
|
|
0 Success
|
|
ERAR_BAD_DATA File CRC error
|
|
ERAR_BAD_ARCHIVE Volume is not valid RAR archive
|
|
ERAR_UNKNOWN_FORMAT Unknown archive format

|
|
|
UCM_CHANGEVOLUME Process volume change.
|
|
|
|
P1 Points to the zero terminated name
|
|
of the next volume.
|
|
|
|
P2 The function call mode:
|
|
|
|
RAR_VOL_ASK Required volume is absent. The function should
|
|
prompt user and return a positive value
|
|
to retry or return -1 value to terminate
|
|
operation. The function may also specify a new
|
|
volume name, placing it to the address specified
|
|
by P1 parameter.
|
|
|
|
RAR_VOL_NOTIFY Required volume is successfully opened.
|
|
This is a notification call and volume name
|
|
modification is not allowed. The function should
|
|
return a positive value to continue or -1
|
|
to terminate operation.

|
|
of RARSetPassword function even for usual
|
|
encrypted files with non-encrypted names.
|
|
|
|
P1 Address pointing to the buffer for a password.
|
|
