KmlDssSymClean?I

Release the internal data structure and point the handle to a null pointer.

Interface Definition

C interface:

int KmlDssSymCleanSI(KmlSolverTask **pHandle);

int KmlDssSymCleanDI(KmlSolverTask **pHandle);

int KmlDssSymCleanCI(KmlSolverTask **pHandle);

int KmlDssSymCleanZI(KmlSolverTask **pHandle);

Parameters

Parameter	Type	Description	Input/Output
pHandle	KmlSolverTask **	Solver handle, which transfers a variable defined previously	Input/Output

Return Value

Return Value	Type	Description
KMLSS_NO_ERROR	int	The execution is successful.
KMLSS_NULL_ARGUMENT	int	Invalid parameter.
KMLSS_BAD_HANDLE	int	The format of pHandle is incorrect.

Dependencies
