eSNMP API Routines
*_get Routine
Field Name
Description
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. The
instance requested is derived by comparing
this OID with the OID in the request found
in the method->varbind->name field. The
oid2instance
function is useful for this.
Description
These types of routines call whatever routine is specified for
Get
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
*_get
method routine is called in response to a
Get
request.
Return Values
ESNMP_MTHD_noError
The routine completed successfully.
ESNMP_MTHD_
noSuchObject
The requested object cannot be returned or does
not exist.
ESNMP_MTHD_
noSuchInstance
The requested instance of an object cannot be
returned or does not exist.
ESNMP_MTHD_genErr
A general processing error.
