| 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. | |
