I found mib2c generated code contains data type mismatch .
Generated structure looks below
/* Typical data structure for a row entry */
struct messageTable_entry {
/* Index values */
long messageIndex;
/* Column values */
U64 sentMsgCount;
long errorMsgCount;
long currentMsgID;
/* Illustrate using a simple linked list */
int valid;
struct messageTable_entry *next;
};
Handler skeleton as below.
int
messageTable_handler(
netsnmp_mib_handler *handler,
netsnmp_handler_registration *reginfo,
netsnmp_agent_request_info *reqinfo,
netsnmp_request_info *requests) {
netsnmp_request_info *request;
netsnmp_table_request_info *table_info;
struct messageTable_entry *table_entry;
switch (reqinfo->mode) {
/*
* Read-support (also covers GetNext requests)
*/
-----------------------------------------------
case MODE_GET:
for (request=requests; request; request=request->next) {
table_entry = (struct messageTable_entry *)
netsnmp_extract_iterator_context(request);
table_info = netsnmp_extract_table_info( request);
switch (table_info->colnum) {
case COLUMN_SENTMSGCOUNT:
if ( !table_entry ) {
netsnmp_set_request_error(reqinfo, request,
SNMP_NOSUCHINSTANCE);
continue;
}
snmp_set_var_typed_integer( request->requestvb, ASN_COUNTER64,
table_entry->sentMsgCount);
break;
---------------------------------------------------------------------------------
}
The problem is with snmp_set_var_typed_integer( request->requestvb,
ASN_COUNTER64,
table_entry->sentMsgCount);
snmp_set_var_typed_integer() expects the 3rd parameter as long .
I think , it should be used as
snmp_set_var_typed_value( request->requestvb, ASN_COUNTER64,
&(table_entry->sentMsgCount),
sizeof(table_entry->sentMsgCount));
Is it wrong ? Please let me know.
Thanks
Sujata
