Hi to all!
This is my first post here!
I'm trying to implement a netsnmp subagent, and I'm having some problems.
I have two tables :
- applicationTypeTable
- applicationTable
The applicationTypeTable has one index: applicationTypeIndex
The applicationTable is indexed by (applicationTypeIndex, applicationIndex)
In my netsnmp subagent code, I have an array to store applicationTypeTable
data, and and double index array to store applicationTable.
I managed to retrieve the data from applicationTypeTable successfully with
this code:
u_char *var_table_app_type(struct variable *vp, oid * name, size_t * length,
int exact,
size_t * var_len, WriteMethod ** write_method)
{
if (header_simple_table
(vp, name, length, exact, var_len, write_method, col_size[vp->magic]))
return (NULL);
int idx = name[*length-1]; ret = NULL; *write_method = 0; u_char
* ret;
switch (vp->magic)
{
case _APPLICATION_TYPE_IDX : //_APPLICATION_TYPE_IDX
pos = _APPLICATION_TYPE_IDX;
*write_method = write_AppTypeTable;
ret = (u_char *) &
applicationTypeTable[idx].applicationTypeIDX;
break;
case _APPLICATION_TYPE_NAME : // _APPLICATION_TYPE_NAME
pos = _APPLICATION_TYPE_NAME;
*var_len = strlen((char
*)applicationTypeTable[idx].applicationTypeNAME);
*write_method = write_AppTypeTable;
ret = (u_char *) &
applicationTypeTable[idx].applicationTypeNAME;
break;
}
return ret;
}
So, to get the data from applicationTypeTable, I get the index with the
name[*length-1];
My main question is :
In my function u_char *var_table_XXX() , how can I retrieve the first and
second indexes of the table applicationTable ?
I tried to use (13 and 14 are the positions of the applicationTypeIndex and
applicationIndex):
idx_app_type = name[13];
idx_app = name[14];
This works for direct GET commands, but doesn't work for GETBULK commands.
Can anyone clarify me ?
Thanks in advance!
