Hi,
I need some help with net-snmp tables handler.
The problem is that I need one single handler function to process SET and GET
commands for several tables of my MIB.
This handler needs to consult an external module to reply to GET, and needs to
pass SET data to an external module for storage. This means that I cannot
create a dataset because the data will be stored externally.
Without a dataset, how can I have one single handler function to process SET
and GET commands for several tables in a MIB.
In the case of scalar values, I used the following from your examples:
[CODE
START]-------------------------------------------------------------------------------------------------------------
struct variable2 example_variables[] = {
{ EXAMPLESTRING, ASN_OCTET_STR, RONLY, var_example, 1, {1}},
{ EXAMPLEINTEGER, ASN_INTEGER, RWRITE, var_example, 2, {2,1}},
...
};
oid example_variables_oid[] = { 1,3,6,1,4,1,2021,254 };
void init_example(void)
{
REGISTER_MIB("example", example_variables, variable2, example_variables_oid);
...
}
u_char *
var_example(struct variable *vp,
oid *name,
size_t *length,
int exact,
size_t *var_len,
WriteMethod **write_method)
{
if (header_generic(vp, name, length, exact, var_len, write_method) ==
MATCH_FAILED)
return NULL;
switch (vp->magic){
case EXAMPLESTRING:
...
return (u_char *) string;
case EXAMPLEINTEGER:
...
return (u_char *) &long_ret;
}
}
[CODE
END]---------------------------------------------------------------------------------------------------------------
Can I use similar approach to tables? In this case how can I manage the row
indexes and how can I declare the table in the array?
Do you have any example of a problem like this that I can use to guide my
development?
Thank you in advance,
Baltazar François
