Is it possible to retrieve an OID from a request in Net-SNMP?
This is to allow the module to identify arguments passed to an OID.
For example, the following OID
```
.1.2.3.4.\"qwerty\"
```
is translated into
```
.1.2.3.4.113.119.101.114.116.121
^^^ ^^^ ^^^ ^^^ ^^^ ^^^
q w e r t y
```
The current implementation lets the `Netsnmp_Node_Handler` process requests
to each registered OID.
This handler takes four parameters:
```c
handle_[NAME OF OBJECT](netsnmp_mib_handler *handler AEGIS_UNUSED,
netsnmp_handler_registration *reginfo AEGIS_UNUSED,
netsnmp_agent_request_info *reqinfo,
netsnmp_request_info *requests);
```
And I couldn't find a way to retrieve an OID from each request.
I tried using `reginfo->rootoid` and `requests->requestvb->name`. However,
they only returned `.1.3.6.1.4` when I registered the handler to a
different OID (`.1.3.6.1.4.1.99999.1.1`).
I found that a function type `FindVarMethod` was used to handle requests in
UCD-SNMP:
```c
unsigned char *var_[NAME OF OBJECT](struct variable *vp, oid *name,
size_t *length, int exact, size_t
*var_len,
WriteMethod **write_method);
```
Is `oid *name` what I'm looking for?
If so, is it possible to do so in Net-SNMP?
Thank you.
