Compress Method

Creates the compressed bzip2 archive.

Syntax

ANSI (Cross Platform)
int Compress();

Unicode (Windows)
INT Compress();
- (void)compress;
#define MID_BZIP2_COMPRESS 4

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

Remarks

Invoking Compress creates the archive specified by ArchiveFile. When the method is called, the file specified by FileDecompressedName will be opened, and the file specified by ArchiveFile will contain the compressed output.

As the data is compressed the Progress event will be fired at regular intervals. This event may be used to stream out the bzip2 file, or to display a progress bar to the user.

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.)
