eSNMP API Routines

*_set Routine

*_set Routine

The *_set method routine for a specified MIB item, which is typically a MIB group (for example, system in MIB II) or a table entry (for example, ifEntry in MIB II).

Format

int mib-group_set ( METHOD *method ) ;

Arguments

method

A pointer to a METHOD structure that contains the following fields:

Field Name

Description

 

 

action

One of ESNMP_ACT_SET,

 

ESNMP_ACT_UNDO, or ESNMP_ACT_

 

CLEANUP.

serial_num

An integer number that is unique to this SNMP

 

request. Each method routine called while

 

servicing a single SNMP request receives the

 

same value as serial_num. New SNMP requests

 

are indicated by a new value of serial_num.

varbind

A pointer to the VARBIND structure that

 

contains the MIB variable’s supplied data value

 

and name (OID). The instance information has

 

already been extracted from the OID and placed

 

in the method->row->instance field.

object

A pointer to the object table entry for

 

the MIB variable being referenced. The

 

method->object->object-index field is this

 

object’s unique index within the object table

 

(useful when one method routine services many

 

objects).

 

The method->object->oid field is the OID

 

defined for this object in the MIB.

flags

A read-only integer bitmask set by the

 

libesnmp routine. If set, the ESNMP_FIRST_

 

IN_ROW bit indicates that this call is the first

 

object to be set in the row. If set, the ESNMP_

 

LAST_IN_ROW bit indicates that this call

 

is the last object to be set in the row. Only

 

METHOD structures with the ESNMP_LAST_

 

IN_ROW bit set are passed to the method

 

routines for commit, undo, and cleanup phases.
