18 | /* This function is called to put an address onto the local or remote transport | |
19 | queue, as appropriate. When the driver is for verifying only, a transport need | |
20 | not be set, in which case it doesn't actually matter which queue the address | |
21 | gets put on. | |
22 | ||
23 | The generic uid/gid options are inspected and put into the address if they are | |
24 | set. For a remote transport, if there are fallback hosts, they are added to the | |
25 | address. | |
26 | ||
27 | Arguments: | |
28 | addr the address, with the transport field set (if not verify only) | |
29 | paddr_local pointer to the anchor of the local transport chain | |
30 | paddr_remote pointer to the anchor of the remote transport chain | |
31 | rblock the router block | |
32 | pw password entry if check_local_user was set, or NULL | |

34 | Returns: FALSE on error; the only case is failing to get a uid/gid | |
