eSNMP API Routines

 

 

*_set Routine

 

 

 

Field Name

Description

 

 

 

row

A pointer to a ROW_CONTEXT structure

 

(defined in the ESNMP.H header file). All Set

 

requests to the method routine that refer to the

 

same group and that have the same instance

 

number will be presented with the same row

 

structure. The method routines can accumulate

 

information in the row structures during Set

 

requests for use during the commit and undo

 

phases. The accumulated data can be released

 

by the method routines during the cleanup

 

phase.

 

 

The ROW_CONTEXT structure contains the

 

following fields:

 

 

instance

An address of an array

 

 

containing the instance OID

 

 

for this conceptual row. The

 

 

libesnmp routine builds this

 

 

array by subtracting the

 

 

object OID from the requested

 

 

variable binding OID.

 

instance_len

The size of the

 

 

method->row->instance field.

 

context

A pointer to be used privately

 

 

by the method routine to

 

 

reference data needed for

 

 

processing this request.

 

save

A pointer to be used privately

 

 

by the method routine to

 

 

reference data needed for

 

 

undoing this request.

 

state

An integer to be used

 

 

privately by the method

 

 

routine for holding any state

 

 

information it requires.

 

 

 

Description

The libesnmp routines call whatever routine is specified for Set operations in the object table identified by the registered subtree.

This function is pointed to by some number of elements of the subagent object table. When a request arrives for an object, its method routine is called. The *_set method routine is called in response to a Set request.
