Dear coders,
I'm sorry to trouble.
I've successfully made my first snmp program on Win2000 platform with
VS2003.
It runs smoothly at the first two hours.
But it suddenly dies after that.
So I changed the snmpget source code so that it runs continuously for about
100,000,000 times.
And I found that the useage of my memory grows quickly.
And it dies some time later.
Would anyone give a right lib so that I can use it?
The source code after changing is like this:
SOCK_STARTUP;
for(i=0;i<10000;i++)
{
for(j=0;j<10000;j++)
{
/*
* Open an SNMP session.
*/
ss = snmp_open(&session);
if (ss == NULL) {
/*
* diagnose snmp_open errors with the input netsnmp_session pointer
*/
snmp_sess_perror("snmpget", &session);
SOCK_CLEANUP;
exit(1);
}
/*
* Create PDU for GET request and add object names to request.
*/
pdu = snmp_pdu_create(SNMP_MSG_GET);
for (count = 0; count < current_name; count++) {
name_length = MAX_OID_LEN;
if (!snmp_parse_oid(names[count], name, &name_length)) {
snmp_perror(names[count]);
failures++;
} else
snmp_add_null_var(pdu, name, name_length);
}
if (failures) {
snmp_close(ss);
SOCK_CLEANUP;
exit(1);
}
/*
* Perform the request.
*
* If the Get Request fails, note the OID that caused the error,
* "fix" the PDU (removing the error-prone OID) and retry.
*/
retry:
status = snmp_synch_response(ss, pdu, &response);
if (status == STAT_SUCCESS) {
if (response->errstat == SNMP_ERR_NOERROR) {
for (vars = response->variables; vars;
vars = vars->next_variable)
{
print_variable(vars->name, vars->name_length, vars);
}
} else {
fprintf(stderr, "Error in packet\nReason: %s\n",
snmp_errstring(response->errstat));
if (response->errindex != 0) {
fprintf(stderr, "Failed object: ");
for (count = 1, vars = response->variables;
vars && count != response->errindex;
vars = vars->next_variable, count++)
/*EMPTY*/;
if (vars) {
fprint_objid(stderr, vars->name, vars->name_length);
}
fprintf(stderr, "\n");
}
exitval = 2;
/*
* retry if the errored variable was successfully removed
*/
if (!netsnmp_ds_get_boolean(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_APP_DONT_FIX_PDUS)) {
pdu = snmp_fix_pdu(response, SNMP_MSG_GET);
snmp_free_pdu(response);
response = NULL;
if (pdu != NULL) {
goto retry;
}
}
} /* endif -- SNMP_ERR_NOERROR */
} else if (status == STAT_TIMEOUT) {
fprintf(stderr, "Timeout: No Response from %s.\n",
session.peername);
exitval = 1;
} else { /* status == STAT_ERROR */
snmp_sess_perror("snmpget", ss);
exitval = 1;
} /* endif -- STAT_SUCCESS */
if (response)
snmp_free_pdu(response);
snmp_close(ss);
}
}
SOCK_CLEANUP;
Any help would be appreciated and thanks in advance.
