#include "ltwrappr.h"

virtual L_INT LVectorBase::EnumGroupsCallBack(pVector, pGroup)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORGROUP pGroup;	/* pointer to a vector group */

Processes each vector group enumerated by the LVectorBase::EnumGroups function.

Parameter	Description
pVector	Pointer to the vector handle that contains the groups to enumerate.
pGroup	Pointer to the vector group being processed.

Returns

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

Comments

The LVectorBase::EnumGroups function calls the callback function as it gets a pointer to each vector group.

To use LVectorBase::EnumGroupsCallBack, derive a class from LVectorBase and override the EnumGroupsCallBack member function. Note that this callback function does not return an LVectorGroupobject.

To get detailed information about each enumerated group, attach pGroup to an LVectorGroup class object and call LVectorGroup::GetGroupDesc.
