Function Documentation

void noleafs_get_object_def	(	u8_t	ident_len,
		s32_t *	ident,
		struct obj_def *	od
	)

dummy function pointers for non-leaf MIB nodes from mib2.c

Definition at line 2075 of file mib2.c.

struct mib_node* snmp_expand_tree	(	struct mib_node *	node,
		u8_t	ident_len,
		s32_t *	ident,
		struct snmp_obj_id *	oidret
	)		`[read]`

Tree expansion.

Definition at line 683 of file mib_structs.c.

void snmp_ifindextonetif	(	s32_t	ifindex,
		struct netif **	netif
	)

Conversion from ifIndex to lwIP netif.

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,
		s32_t *	ident
	)

Conversion from lwIP ip_addr to oid.

Parameters:

ident	points to s32_t ident[4] output

Definition at line 147 of file mib_structs.c.

u8_t snmp_iso_prefix_expand	(	u8_t	ident_len,
		s32_t *	ident,
		struct snmp_obj_id *	oidret
	)

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!!

Definition at line 1140 of file mib_structs.c.

u8_t snmp_iso_prefix_tst	(	u8_t	ident_len,
		s32_t *	ident
	)

Test object identifier for the iso.org.dod.internet prefix.

Parameters:

ident_len	the length of the supplied object identifier
ident	points to the array of sub identifiers

Returns:: 1 if it matches, 0 otherwise

Definition at line 1114 of file mib_structs.c.

struct mib_list_rootnode* snmp_mib_node_delete	(	struct mib_list_rootnode *	rn,
		struct mib_list_node *	n

Removes node from idx list if it has a single child left.

Parameters:

rn	points to the root node
n	points to the node to delete

Returns:: the nptr to be freed by caller

Definition at line 395 of file mib_structs.c.

s8_t snmp_mib_node_find	(	struct mib_list_rootnode *	rn,
		s32_t	objid,
		struct mib_list_node **	fn
	)

Finds node in idx list and returns deletion mark.

Parameters:

rn	points to the root node
objid	is the object sub identifier
fn	returns pointer to found node

Returns:: 0 if not found, 1 if deletable, 2 can't delete (2 or more children), 3 not a list_node

Definition at line 338 of file mib_structs.c.

s8_t snmp_mib_node_insert	(	struct mib_list_rootnode *	rn,
		s32_t	objid,
		struct mib_list_node **	insn
	)

Inserts node in idx list in a sorted (ascending order) fashion and allocates the node if needed.

Parameters:

rn	points to the root node
objid	is the object sub identifier
insn	points to a pointer to the inserted node used for constructing the tree.

Returns:: -1 if failed, 1 if inserted, 2 if present.

Definition at line 216 of file mib_structs.c.

void snmp_netiftoifindex	(	struct netif *	netif,
		s32_t *	ifidx
	)

Conversion from lwIP netif to ifIndex.

Parameters:

netif	points to a netif struct
ifidx	points to s32_t object sub-identifier

Definition at line 116 of file mib_structs.c.

void snmp_oidtoip	(	s32_t *	ident,
		ip_addr_t *	ip
	)

Conversion from oid to lwIP ip_addr.

Parameters:

ident	points to s32_t ident[4] input
ip	points to output struct

Definition at line 136 of file mib_structs.c.

struct mib_node* snmp_search_tree	(	struct mib_node *	node,
		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:: pointer to the requested parent (!) node if success, NULL otherwise
