L_INT LVectorObject::GetHyperlink(uIndex, pTarget)

L_UINT32 uIndex;	/* index in the target list */
pVECTORLINKDESC pTarget;	/* pointer to structure that will receive the hyperlink target information */

Gets information about one of the targets in the target list of a hyperlinked vector object.

Parameter	Description
uIndex	Index in the target list.
pTarget	Pointer to a VECTORLINKDESC structure to be updated with the hyperlink target information.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
