2. The base OID for objects to be sent in traps.

The provided trap object contains the bindings to be sent with the

|
trap. The base OID will be prefixed to the provided OID and, if the

length is positive, the requested OID is assumed to be a columnar
|
|
object and the index OID will be appended.

The two first arguments are the MIB registry used to locate the trap

objects.

The use of the arguments may differ depending on the implementation

used.
