  Similar to RARReadHeader, but uses RARHeaderDataEx structure,
containing information about Unicode file names and 64 bit file sizes.
 
struct RARHeaderDataEx
{
  char         ArcName[1024];

int PASCAL RARProcessFile(HANDLE hArcData,
                          int Operation,
                          char *DestPath,
                          char *DestName)
====================================================================
 
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
  of the file to be extracted or NULL as default. If DestName is defined
  (not NULL) it overrides the original file name saved in the archive and  
  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
  ERAR_EOPEN            Volume open error
  ERAR_ECREATE          File create error
  ERAR_ECLOSE           File close error
  ERAR_EREAD            Read error
  ERAR_EWRITE           Write error
 
 
Note: if you wish to cancel extraction, return -1 when processing
      UCM_PROCESSDATA callback message.
 
 
====================================================================
int PASCAL RARProcessFileW(HANDLE hArcData,
                           int Operation,
                           wchar_t *DestPath,
                           wchar_t *DestName)
====================================================================
 
Description
~~~~~~~~~~~
  Unicode version of RARProcessFile. It uses Unicode DestPath
  and DestName parameters, other parameters and return values
  are the same as in RARProcessFile.
 
 
====================================================================
void PASCAL RARSetCallback(HANDLE hArcData,
            int PASCAL (*CallbackProc)(UINT msg,LONG UserData,LONG P1,LONG P2),
            LONG UserData);
====================================================================
 
Description
~~~~~~~~~~~
  Set a user-defined callback function to process Unrar events.
 
Parameters
~~~~~~~~~~
hArcData
  This parameter should contain the archive handle obtained from the
  RAROpenArchive function call.
 
CallbackProc
  It should point to a user-defined callback function.
 
  The function will be passed four parameters:
 
 
  msg                    Type of event. Described below.
 
  UserData               User defined value passed to RARSetCallback.
 
  P1 and P2              Event dependent parameters. Described below.
 
 
  Possible events
 
    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.  
 
    UCM_PROCESSDATA          Process unpacked data. It may be used to read
                             a file while it is being extracted or tested
                             without actual extracting file to disk.
                             Return a positive value to continue process
                             or -1 to cancel the archive operation
 
      P1                   Address pointing to the unpacked data.
                           Function may refer to the data but must not
                           change it.
 
      P2                   Size of the unpacked data. It is guaranteed
                           only that the size will not exceed the maximum
                           dictionary size (4 Mb in RAR 3.0).
 
    UCM_NEEDPASSWORD         DLL needs a password to process archive.
                             This message must be processed if you wish
                             to be able to handle archives with encrypted
                             file names. It can be also used as replacement
                             of RARSetPassword function even for usual
                             encrypted files with non-encrypted names.
 
      P1                   Address pointing to the buffer for a password.
                           You need to copy a password here.
 
      P2                   Size of the password buffer.
 
 
UserData
  User data passed to callback function.
 
  Other functions of UnRAR.dll should not be called from the callback
  function.
 
Return values
~~~~~~~~~~~~~
  None
 
 
 
====================================================================
void PASCAL RARSetChangeVolProc(HANDLE hArcData,
            int PASCAL (*ChangeVolProc)(char *ArcName,int Mode));
====================================================================
 
Obsoleted, use RARSetCallback instead.
 
 
 
====================================================================
void PASCAL RARSetProcessDataProc(HANDLE hArcData,
            int PASCAL (*ProcessDataProc)(unsigned char *Addr,int Size))
====================================================================
 
Obsoleted, use RARSetCallback instead.
 
 
====================================================================
void PASCAL RARSetPassword(HANDLE hArcData,
                           char *Password);
====================================================================
 
Description
~~~~~~~~~~~
  Set a password to decrypt files.
 
Parameters
~~~~~~~~~~
hArcData
  This parameter should contain the archive handle obtained from the
  RAROpenArchive function call.
 
Password
  It should point to a string containing a zero terminated password.
 
Return values
~~~~~~~~~~~~~
  None
 
 
====================================================================
void PASCAL RARGetDllVersion();
====================================================================
 
Description
~~~~~~~~~~~
  Returns API version.
 
Parameters
~~~~~~~~~~
  None.
 
Return values
~~~~~~~~~~~~~
  Returns an integer value denoting UnRAR.dll API version, which is also
defined in unrar.h as RAR_DLL_VERSION. API version number is incremented
only in case of noticeable changes in UnRAR.dll API. Do not confuse it
with version of UnRAR.dll stored in DLL resources, which is incremented
with every DLL rebuild.
 
  If RARGetDllVersion() returns a value lower than UnRAR.dll which your
application was designed for, it may indicate that DLL version is too old
and it will fail to provide all necessary functions to your application.
 
  This function is absent in old versions of UnRAR.dll, so it is safer
to use LoadLibrary and GetProcAddress to access this function.
