Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
int AppendFiles();

Unicode (Windows)
INT AppendFiles();

- (void)appendFiles;

#define MID_SEVENZIP_APPENDFILES 3

IPWORKSZIP_EXTERNAL int IPWORKSZIP_CALL IPWorksZip_SevenZip_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

All files contained in the Files collection will be appended to the archive specified by ArchiveFile.

When AppendFiles is called, only those files which are to be added to the archive must exist inside the collection. Note that if you call Scan or Extract, you must empty the collection before adding files to the collection to be appended.

After the file is added, the collection will be updated appropriately.

This method may only be used to add files to an existing archive. To add files to a new archive, the IncludeFiles and Compress methods should be used.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
