EDCS CloneAttributeValue

EDCS Reference Manual Functions EDCS CloneAttributeValue

extern EDCS_Status_Code
EDCS_CloneAttributeValue
(
const	EDCS_Attribute_Value	*	src_ptr,	¹
	EDCS_Attribute_Value	*	dest_ptr	²
);

Definition

Clones the data from *src_ptr into *dest_ptr, by allocating memory for any necessary internal pointers within *dest_ptr, then populating *dest_ptr with data from *src_ptr.

IMPORTANT NOTES:

Because some of the fields contained in the data structure are pointers to dynamically allocated memory, it is HIGHLY INADVISABLE to use a member-wise structure copy in order to duplicate an EDCS_Attribute_Value structure. In order to reliably duplicate this data, developers should use the EDCS_CloneAttributeValue() function.
The caller is responsible for calling EDCS_FreeAttributeValue() to free the internal pointers allocated within *dest_ptr.

Returns

EDCS_SC_SUCCESS	and memory is allocated for any dynamically allocated data within the structure, and it is populated with data copied from *src_ptr, if valid parameters were passed in.
EDCS_SC_NULL_REQUIRED_PARAMETER	and *dest_ptr is left unchanged, if dest_ptr or src_ptr was NULL.
EDCS_SC_OTHER_FAILURE	and *dest_ptr is set to its (empty) default value, if the API could not allocate the memory for the dynamically allocated memory it should refer to.

Parameters Notes

¹ the EDCS_Attribute_Value that is to be duplicated

² a pointer to an EDCS_Attribute_Value structure within memory managed by the caller. Non-dynamically allocated fields in this structure will be directly populated with data from the input fields. Dynamically allocated data will be allocated by this function, then copied from the input structure.
