#include "lvkrn.h"

L_INT EXT_FUNCTION L_VecSetGroup(pVector, pGroup, pGroupDesc)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
const pVECTORGROUP pGroup;	/* pointer to a vector group */
const pVECTORGROUPDESC pGroupDesc;	/* pointer to a structure */

Updates a vector group with new information. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
pVector	Pointer to the vector handle.
pGroup	Pointer to a VECTORGROUP structure that references the vector group to set.
pGroupDesc	Pointer to a VECTORGROUPDESC structure that contains the new group information to set.

Returns

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

Example

/* This example will change the name of a given group */
void LockGroup( pVECTORHANDLE pVector, const L_TCHAR *pszOldName, const L_TCHAR *pszNewName )
{
   VECTORGROUP       Group;
   VECTORGROUPDESC   GroupDesc;
   L_INT             nRet;

   /* find the group with that name */
   nRet = L_VecGetGroupByName( pVector, pszOldName, &Group );
   if( nRet != SUCCESS )
      return;  /* group not found */

   /* get this group for editing */
   L_VecGetGroup( pVector, &Group, &GroupDesc );

   /* set new name */
   lstrcpy( GroupDesc.szName, pszNewName );

   /* set back and clean up */
   L_VecSetGroup( pVector, &Group, &GroupDesc );
   L_VecFreeGroup( &GroupDesc );
