snmp_node_instance Struct Reference
SNMP node instance. More...
#include <snmp_core.h>
Data Fields | |
| struct snmp_node * | node |
| prefilled with the node, get_instance() is called on; may be changed by user to any value to pass an arbitrary node between calls to get_instance() and get_value/test_value/set_value | |
| struct snmp_obj_id | instance_oid |
| prefilled with the instance id requested; for get_instance() this is the exact oid requested; for get_next_instance() this is the relative starting point, stack expects relative oid of next node here | |
| u8_t | asn1_type |
| ASN type for this object (see snmp_asn1.h for definitions) | |
| snmp_access_t | access |
| one out of instance access types defined above (SNMP_NODE_INSTANCE_READ_ONLY,...) | |
| node_instance_get_value_method | get_value |
| returns object value for the given object identifier. | |
| node_instance_set_test_method | set_test |
| tests length and/or range BEFORE setting | |
| node_instance_set_value_method | set_value |
| sets object value, only called when set_test() was successful | |
| node_instance_release_method | release_instance |
| called in any case when the instance is not required anymore by stack (useful for freeing memory allocated in get_instance/get_next_instance methods) | |
| union snmp_variant_value | reference |
| reference to pass arbitrary value between calls to get_instance() and get_value/test_value/set_value | |
| u32_t | reference_len |
| see reference (if reference is a pointer, the length of underlying data may be stored here or anything else) | |
