This closes everything.

Returns: Return Codes

◆ DisableMsgLogging()

void xb::xbXBase::DisableMsgLogging ( )

void xb::xbSsv::DisplayError ( xbInt16 iErrorCode ) const

inherited

Display error message on console for a given error number.

Parameters

iErrorCode Error number to reference

void xb::xbXBase::EnableMsgLogging ( )

◆ FlushLog()

xbInt16 xb::xbXBase::FlushLog ( )

inherited

Get the current data directory.

Returns: xbString containing the current data directory where the database files are stored.

◆ GetDbfPtr() [1/2]

xbDbf * xb::xbTblMgr::GetDbfPtr ( const xbString & sTblAlias ) const

inherited

◆ GetDbfPtr() [2/2]

inherited

◆ GetDefaultAutoCommit()

xbBool xb::xbSsv::GetDefaultAutoCommit ( ) const

inherited

Get the default auto commit setting.

When auto commit is enabled, the library will automatically post any updates when moving off an updated record or closing files. If auto commit is disabled, the application program will need to explicitly update the tables using using dbf->Put() and dbf->AppendRecord().

Returns: xbTrue if auto commit is turned on
xbFalse is auto commit is turned off

inherited

◆ GetDefaultLogFileName()

xbString & xb::xbSsv::GetDefaultLogFileName ( ) const

inherited

◆ GetEndianType()

xbInt16 xb::xbSsv::GetEndianType ( ) const

inherited

Get the Endian type.

Returns: B - Big endian
L - Little endian

◆ GetErrorMessage()

const char * xb::xbSsv::GetErrorMessage ( xbInt16 iErrorCode ) const

inherited

Get an error message.

Parameters

iErrorCode ErrorCode is the error number of description to be returned.

Returns: Returns a pointer to a string containing a text description for the error code.

◆ GetFunctionInfo()

		char &	cReturnType,
		xbInt16 &	iReturnLenCalc,
		xbInt32 &	lReturnLenVal
	)		const

protected

◆ GetLogFileName()

const xbString & xb::xbXBase::GetLogFileName ( ) const

◆ GetLogFqFileName()

const xbString & xb::xbXBase::GetLogFqFileName ( ) const

◆ GetLogStatus()

xbBool xb::xbXBase::GetLogStatus ( ) const

◆ GetMultiUser()

xbBool xb::xbSsv::GetMultiUser ( ) const

inherited

Get the multi user setting.

Returns: xbTrue - Multi user mode turned on.
xbFalse - Multi user mode turned off.

◆ GetOpenTableCount()

xbInt16 xb::xbTblMgr::GetOpenTableCount ( ) const

inherited

◆ Open() [1/2]

xbDbf * xb::xbXBase::Open	(	const xbString &	sTableName,
		const xbString &	sAlias,
		xbInt16	iOpenMode,
		xbInt16	iShareMode,
		xbInt16	iRequestVersion,
		xbInt16 &	iRc
	)

Open highest qualified class available for dbf file.

This routine can open various versions of the dbf file dependent on the iVersion field

Parameters

sTableName	- Table name to open.
sAlias	- Optional alias name.
iOpenMode	- XB_READ_WRITE or XB_READ
iShareMode	- XB_SINGLE_USER or XB_MULTI_USER
iRequestVersion	0 - Highest available 4 - Version four dbf 3 - Version three dbf
iRc	- Return code from open request

Returns: param dbf - Output pointer to dbf file opened or null if error

◆ Open() [2/2]

xbDbf * xb::xbXBase::Open	(	const xbString &	sTableName,
		xbInt16 &	iRc
	)

Open highest qualified class available for dbf file.

This routine opens the highest available version of the dbf file. Defaults to XB_READ_WRITE and XB_MULTI_USER mode.

Returns: param dbf - Output pointer to dbf file opened or null if error

◆ OpenHighestVersion() [1/2]

xbInt16 xb::xbXBase::OpenHighestVersion	(	const xbString &	sTableName,
		const xbString &	sAlias,
		xbDbf &	dbf,
		int	dummy
	)

inherited

◆ RemoveTblFromTblList() [2/2]

xbInt16 xb::xbTblMgr::RemoveTblFromTblList ( xbDbf * d )

inherited

◆ SetDataDirectory()

void xb::xbSsv::SetDataDirectory ( const xbString & sDataDirectory )

inherited

Set the data directory.

Parameters

sDataDirectory Set the data direcroty.

◆ SetDefaultAutoCommit()

void xb::xbSsv::SetDefaultAutoCommit ( xbBool bDefaultAutoCommit )

inherited

Set the default auto commit.

Disabling auto commit requires the application execute explicit updates using dbf->Put() and dbf->AppendRecord(). With auto commit on, the library posts updates automatically when moving off the current record or closing a file.

Parameters

bDefaultAutoCommit xbTrue - Enable default auto commit.
xbFalse - Disable default auto commit.

◆ SetDefaultDateFormat()

void xb::xbSsv::SetDefaultDateFormat ( const xbString & sDefaultDateFormat )

inherited

Set the default date format.

Parameters

sDefaultDateFormat Set the default date format.

◆ SetDefaultLogDirectory()

void xb::xbSsv::SetDefaultLogDirectory ( const xbString & sDefaultLogDirectory )

inherited

◆ SetEndianType()

void xb::xbSsv::SetEndianType ( )

protectedinherited

Set the endian type.

This routine determines the Endian-ness at run time instead of compile time as some processers (ie; Sparc,ARM) can be switched either way. This routine is called automatically by the library at startup and does not need to be called in an application program.

◆ SetLogDirectory()

void xb::xbXBase::SetLogDirectory ( const xbString & sLogFileDirectory )

◆ SetLogFileName()

void xb::xbXBase::SetLogFileName ( const xbString & sLogFileName )

◆ SetLogSize()

void xb::xbXBase::SetLogSize ( size_t lSize )

◆ SetMultiUser()

void xb::xbSsv::SetMultiUser ( xbBool bMultiUser )

inherited

Get the multi user setting.

Parameters

bMultiUser xbTrue - Turn on Multi user mode.
xbFalse - Turn off Multi user mode.

◆ WriteLogBytes()

xbInt16 xb::xbXBase::WriteLogBytes	(	xbUInt32	lCnt,
		const char *	p
	)

◆ WriteLogMessage()

xbInt16 xb::xbXBase::WriteLogMessage	(	const xbString &	sLogMessage,
		xbInt16	iOutputOpt = `0`
	)

◆ xbMemcmp()

		const unsigned char *	s2,
		size_t	n
	)

s2	Right operand to compare.
n	Number of bytes to compare.

Returns: 1 s1 > s2
0 s1 == s2
-1 s1 < s2

◆ xbSleep()

void xb::xbXBase::xbSleep ( xbInt32 lMillisecs )

Cross platform sleep function.

Parameters

lMillisecs Milliseconds to sleep.
