61 /* Some details about chaining: | |
62 * | |
63 * A message is made of a header ( msg ) and 0 or more AVPs ( avp ). | |
64 * The structure is a kind of tree, where some AVPs (grouped AVPs) can contain other AVPs. | |
871 | 65 * Example: |
0 | 66 * msg |
67 * |-avp | |
68 * |-gavp | |
69 * | |-avp | |
70 * | |-avp | |
71 * | \-avp | |
72 * |-avp | |
73 * \-avp | |
74 * | |
75 * Each item (msg or avp) structure begins with a msg_avp_chain structure. | |
76 * The element at the top of the hierarchy (msg in our example) has all the fields of its "chaining" equal to the same value. | |
77 * | |
78 * All elements at the same level are linked by their "chaining" list. | |
79 * The "children" list is the sentinel for the lists of children of this element. | |
