- Parameters:
-
ifindex is a s32_t object sub-identifier netif points to returned netif struct pointer
Definition at line 95 of file mib_structs.c.
| void snmp_iptooid | ( | ip_addr_t * | ip, |

| u8_t snmp_iso_prefix_expand | ( | u8_t | ident_len, |

Expands object identifier to the iso.org.dod.internet prefix for use in getnext operation.
- Parameters:
-
ident_len the length of the supplied object identifier ident points to the array of sub identifiers oidret points to returned expanded object identifier
- Returns:
- 1 if it matches, 0 otherwise
- Note:
- ident_len 0 is allowed, expanding to the first known object id!!

| u8_t | ident_len, | ||
| s32_t * | ident, | ||
| struct snmp_name_ptr * | np | ||
| ) | [read] |
Searches tree for the supplied (scalar?) object identifier.
- Parameters:
-
node points to the root of the tree ('.internet') ident_len the length of the supplied object identifier ident points to the array of sub identifiers np points to the found object instance (return)
- Returns:
