95 * The subtree structure contains a subtree prefix which applies to
96 * all variables in the associated variable list.
98 * By converting to a tree of subtree structures, entries can
99 * now be subtrees of another subtree in the structure. i.e:
104 oid name[16]; /* objid prefix of registered subtree */
105 u_char namelen; /* number of subid's in name above */
106 oid start[16]; /* objid of start of covered range */
107 u_char start_len; /* number of subid's in start name */
108 oid end[16]; /* objid of end of covered range */
109 u_char end_len; /* number of subid's in end name */
110 struct variable *variables; /* pointer to variables array */
111 int variables_len; /* number of entries in above array */
112 int variables_width; /* sizeof each variable entry */
113 char label[256]; /* calling module's label */
114 struct snmp_session *session;
117 struct subtree *next; /* List of 'sibling' subtrees */
118 struct subtree *prev; /* Make siblings a doubly-linked list */
119 struct subtree *children; /* List of 'child' subtrees */
123 * This is a new variable structure that doesn't have as much memory
124 * tied up in the object identifier. It's elements have also been re-arranged
125 * so that the name field can be variable length. Any number of these
126 * structures can be created with lengths tailor made to a particular
127 * application. The first 5 elements of the structure must remain constant.
