.PP
This function registers an instance helper handler, which is a way of registering an exact OID such that GENEXT requests are handled entirely by the helper. First need to inject it into the calling chain of the handler defined by the netsnmp_handler_registration struct, reginfo. The new handler is injected at the top of the list and will be the new handler to be called first. This function also injects a serialize handler before actually calling netsnmp_register_handle, registering reginfo.

This function registers an int helper handler to a specified OID. \fBParameters:\fP
.RS 4
\fIname\fP the name used for registration pruposes.
.br
\fIreg_oid\fP the OID where you want to register your integer at
.br
\fIreg_oid_len\fP the length of the OID

\fIit\fP the integer value to be registered during initialization
.br
\fIsubhandler\fP a handler to do whatever you want to do, otherwise use NULL to use the default int handler.

.SS "int netsnmp_register_read_only_instance (\fBnetsnmp_handler_registration\fP * reginfo)"
.PP
This function injects a 'read only' handler into the handler chain prior to serializing/registering the handler. The only purpose of this 'read only' handler is to return an appropriate error for any requests passed to it in a SET mode. Inserting it into your handler chain will ensure you're never asked to perform a SET request so you can ignore those error conditions.

\fBParameters:\fP
.RS 4
\fIreginfo\fP a handler registration structure which could get created using netsnmp_create_handler_registration. Used to register a read only instance helper handler.

\fBReturns:\fP
.RS 4
MIB_REGISTERED_OK is returned if the registration was a success. Failures are MIB_REGISTRATION_FAILED and MIB_DUPLICATE_REGISTRATION.
