Functions
int snmp_oid_compare
(const oid *in_name1, size_t len1, const oid *in_name2,
size_t len2)
lexicographical compare two object identifiers.
int snmp_oidtree_compare (const oid *in_name1, size_t
len1, const oid *in_name2, size_t len2)
Compares 2 OIDs to determine if they are equal up until the
shortest length.
int netsnmp_oid_equals (const oid *in_name1, size_t
len1, const oid *in_name2, size_t len2)
Compares 2 OIDs to determine if they are exactly equal.
int netsnmp_oid_is_subtree (const oid *in_name1,
size_t len1, const oid *in_name2, size_t len2)
Identical to netsnmp_oid_equals, except only the length up
to len1 is compared.
int netsnmp_oid_find_prefix (const oid *in_name1,
size_t len1, const oid *in_name2, size_t len2)
Given two OIDs, determine the common prefix to them
both.
#define
DEBUGPRINTPDUTYPE(token, type)
Value:
switch(type) { case SNMP_MSG_GET: DEBUGDUMPSECTION(token, ’PDU-GET’); break; case SNMP_MSG_GETNEXT: DEBUGDUMPSECTION(token, ’PDU-GETNEXT’); break; case SNMP_MSG_RESPONSE: DEBUGDUMPSECTION(token, ’PDU-RESPONSE’); break; case SNMP_MSG_SET: DEBUGDUMPSECTION(token, ’PDU-SET’); break; case SNMP_MSG_GETBULK: DEBUGDUMPSECTION(token, ’PDU-GETBULK’); break; case SNMP_MSG_INFORM: DEBUGDUMPSECTION(token, ’PDU-INFORM’); break; case SNMP_MSG_TRAP2: DEBUGDUMPSECTION(token, ’PDU-TRAP2’); break; case SNMP_MSG_REPORT: DEBUGDUMPSECTION(token, ’PDU-REPORT’); break; default: DEBUGDUMPSECTION(token, ’PDU-UNKNOWN’); break; }

#define
timercmp(tvp, uvp, cmp)
Value:
((tvp)->tv_sec cmp (uvp)->tv_sec || ((tvp)->tv_sec == (uvp)->tv_sec && (tvp)->tv_usec cmp (uvp)->tv_usec))

int
netsnmp_oid_equals (const oid * in_name1, size_t len1, const
oid * in_name2, size_t len2)
Compares 2 OIDs to determine if they are exactly equal.
This should be faster than doing a snmp_oid_compare for different length OIDs, since the length is checked first and if != returns immediately. Might be very slighly faster if lengths are ==.
Parameters:
in_name1
A pointer to the first oid.
len1 |
length of the first OID (in segments, not bytes) |
in_name2
A pointer to the second oid.
len2 |
length of the second OID (in segments, not bytes) |
Returns:
0 if they are equal, 1 if they are not.

int
netsnmp_oid_find_prefix (const oid * in_name1, size_t len1,
const oid * in_name2, size_t len2)
Given two OIDs, determine the common prefix to them
both.
Parameters:
in_name1
A pointer to the first oid.
len1 |
Length of the first oid. |
in_name2
A pointer to the second oid.
len2 |
Length of the second oid. |
Returns:
length of largest common index of commonality. 1 = first, 0 if none * or -1 on error.
Definition at line 6100 of file snmp_api.c.
int
netsnmp_oid_is_subtree (const oid * in_name1, size_t len1,
const oid * in_name2, size_t len2)
Identical to netsnmp_oid_equals, except only the length up
to len1 is compared.
Functionally, this determines if in_name2 is equal or a subtree of in_name1
Parameters:
in_name1
A pointer to the first oid.
len1 |
length of the first OID (in segments, not bytes) |
in_name2
A pointer to the second oid.
len2 |
length of the second OID (in segments, not bytes) |
Returns:
0 if one is a common prefix of the other.

int
snmp_oid_compare (const oid * in_name1, size_t len1, const
oid * in_name2, size_t len2)
lexicographical compare two object identifiers.
Caution: this method is called often by command responder applications (ie, agent).
Returns:
-1 if name1 < name2, 0 if name1 = name2, 1 if name1 > name2

int
snmp_oidtree_compare (const oid * in_name1, size_t len1,
const oid * in_name2, size_t len2)
Compares 2 OIDs to determine if they are equal up until the
shortest length.
Parameters:
in_name1
A pointer to the first oid.
len1 |
length of the first OID (in segments, not bytes) |
in_name2
A pointer to the second oid.
len2 |
length of the second OID (in segments, not bytes) |
Returns:
0 if they are equal, 1 if in_name1 is > in_name2, or -1 if <.
