#include "ltwrappr.h"
virtual L_INT LVectorBase::EnumGroupsCallBack(pVector, pGroup)

Pointer to the vector group being processed.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
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.
For an example, refer to LVectorBase::EnumGroups.
