pszFileName	Name of .DAT file
lFlags	Flags for open, and encryption, etc.

Returns: Error return code

◆ releaseFile()

ErrorCode Bagel::SpaceBar::CBofDataFile::releaseFile ( )

Free memory used by this object

Returns: Error return code

◆ getRecSize()

int32 Bagel::SpaceBar::CBofDataFile::getRecSize ( int32 lRecNum )

Retrieves size of specified record.

Parameters

lRecNum Index of record to get size of

Returns: Size of specified record

◆ getMaxRecSize()

int32 Bagel::SpaceBar::CBofDataFile::getMaxRecSize ( ) const

Retrieves size of the largest record.

Returns: Error return code

◆ close()

ErrorCode Bagel::SpaceBar::CBofDataFile::close ( )

overridevirtual

Closes current data-file, if it's not already closed

Returns: Error return code

Reimplemented from Bagel::SpaceBar::CBofFile.

◆ create()

ErrorCode Bagel::SpaceBar::CBofDataFile::create ( )

Destroys current data-file, if any, and starts a new empty one

Returns: Error return code

◆ readRecord()

ErrorCode Bagel::SpaceBar::CBofDataFile::readRecord	(	int32	lRecNum,
		void *	pBuf
	)

Reads specified record from data-file.

Parameters

lRecNum	Record number to read
