esnmp_unregister
esnmp_unregister
Cancels registration of a MIB subtree previously registered with the master
agent.
Format
int esnmp_unregister ( SUBTREE *subtree );
Arguments
subtree
A pointer to a subtree structure corresponding to the subtree to be handled.
The code emitted by the MIB compiler files (subtree_TBL.C and subtree_TBL.H)
externally declare and initialize the subtree structures. Refer to Chapter 3 for
more information about these files.
Description
This routine can be called by the application code to tell the eSNMP subagent
not to process requests for variables in this MIB subtree anymore. You can later
reregister a MIB subtree, if needed, by calling the
esnmp_register
routine.
Return Values
SNMP_LIB_OK The
esnmp_unregister
routine has completed
successfully.
ESNMP_LIB_BAD_REG The MIB subtree was not registered.
ESNMP_LIB_LOST_
CONNECTION
The request to unregister the MIB subtree could
not be sent. You should restart the protocol.
Example
#include <esnmp.h>
int status
extern SUBTREE ipRouteEntry_subtree;
status = esnmp_unregister (&ipRouteEntry_subtree);
switch (status) {
case ESNMP_LIB_OK:
printf ("The esnmp_unregister routine completed successfully.\n");
break;
case ESNMP_LIB_BAD_REG:
printf ("The MIB subtree was not registered.\n");
case ESNMP_LIB_LOST_CONNECTION:
printf ("%s%s%s\n", "The request to unregister the ",
"MIB subtree could not be sent. ",
"You should restart the protocol.\n");
break;
}
