DG_InitConfigOpts

Initializes DataGuard's configuration function group.

int DG_InitConfigOpts ( 
   	DG_BusinessType type, 
        DG_ConfigOpts **opts
   )

**Table 1** Description
Parameter	Description	Value Range	Input/Output
type	Indicates the DataGuard component type, which is DG_BusinessType.	For cryptographic computing, the relevant enumerator leverages KCAL.	Input
opts	Indicates DataGuard's configuration function group. For details, see Table 2.	It is null as a single pointer and cannot be null as a double pointer.	Output

**Table 2** DG_ConfigOpts structure
Member	Type	Description
init	Function pointer	int (init)(DG_Cfg config); Initializes the config object.
release	Function pointer	int (release)(DG_Cfg config); Releases the config object.
setIntValue	Function pointer	int (setIntValue)(DG_Cfg config, const char key, int value); Sets the int value using a key-value pair.
setVoidValue	Function pointer	int (setVoidValue)(DG_Cfg config, const char key, const DG_Void* value); Sets the void value using a key-value pair.

**Table 3** Error codes
Error Code	Value	Description	Remarks
DG_ERR_CONFIG_PARAM	62	Failed to verify input parameters.	-
DG_ERR_CONFIG_DG_BUSINESS_TYPE	61	The type is incorrect.	For cryptographic computing, the relevant enumerator leverages KCAL.
