Re: Register_int handler

Hi,

Is there any place I could find specifications for the custom handlers (calling conventions, return values, etc)?

TIA
Nikos

    Hi,

    During development of my own handlers, after putting a trace on the handler I notice that it is called 4 times during an snmpset operation. 2 with the old value and 2 with the new value. This apart from dangerous, seems a waste of resources to do a simple set. What instance does each call respresent? Can I avoid it? Am I doing something wrong?

    Server2:~/work/snmp-> snmpset 127.0.0.1 iwSetMode = 4
    IANWAP-MIB::iwSetMode = INTEGER: restart(4)
    .
    .
    .
    nkssnmpd: info: setMode ~> mode = 3
    nkssnmpd: info: setMode ~> mode = 3
    nkssnmpd: info: setMode ~> mode = 4
    nkssnmpd: info: setMode ~> mode = 4
    .
    .
    .

    My registration. mode is a static enum:

    netsnmp_register_int_instance("iwSetMode",
                                                 mode_oid,
                                                OID_LENGTH(mode_oid),
                                                (void *)&mode, (void *)setMode);

    PS I would love to pass arguments to setMode, but I have tried several function pointers (i.e. void (*setMode)(int mode)) and don't work. Any suggestions on that?

    Thanx,
    Nikos
