Extract Method

Extracts the compressed file from the bzip2 archive.

Syntax

ANSI (Cross Platform)
int Extract();

Unicode (Windows)
INT Extract();
- (void)extract;
#define MID_BZIP2_EXTRACT 6

IPWORKSZIP_EXTERNAL int IPWORKSZIP_CALL IPWorksZip_Bzip2_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Invoking Extract decompresses the archive specified by ArchiveFile. The compressed file will be extracted, and written to disk.

If FileDecompressedName is set to a nonempty string the file will be written there. Otherwise the class will automatically set FileDecompressedName to an appropriate value:

If ArchiveFile ends in ".bz2", this filename, less the ".bz2" extension will be used.

If this condition does not hold, ".unzipped" will be appended to ArchiveFile.

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.)
