|
||||||
|
* sysdep.h (CLOSE): Don't call close on file descriptors less than
|
||||||
|
0, i.e. on uncreated sockets.
|
||||||
|
|
||||||
|
* connect.c (resolve_bind_address): Work on struct sockaddr
|
||||||
|
directly.
|
||||||
|
(connect_to_host): Replacement for connect_to_many. Resolve HOST
|
||||||
|
and connect to any of its addresses. If we can't connect and the
|
||||||
|
host name lookup was cached, try to resolve it again. This should
|
||||||
|
fix problems with hosts behind dynamic DNS. Updated all callers.
|
||||||
|
(connect_to_ip): Replacement for connect_to_one. Removed SILENT;
|
||||||
|
added the argument PRINT instead. Updated all callers.
|
||||||
|
(set_connection_host_name): Removed.
|
||||||
|
|
||||||
|
* host.c (address_list_address_at): New function instead of
|
||||||
|
address_list_copy_one. It returns a pointer to ip_address *, so
|
||||||
|
it's not necessary to copy the data.
|
||||||
|
(address_list_cached_p): New function.
|
||||||
|
(forget_host_lookup): Ditto.
|
||||||
|
|
||||||
|
* connect.c: Got rid of the MSOCK global variable. Made bindport
|
||||||
|
return the local socket it creates. Added a new argument to
|
||||||
|
acceptport, the socket to call accept on. Updated callers.
|
||||||
|
(closeport): Removed.
|
||||||
|
|
||||||
|
* connect.c: Moved the sockaddr code from host.c to this file,
|
||||||
|
because most of that stuff is used for connecting, and has nothing
|
||||||
|
to do with host names anyway.
|
||||||
|
(sockaddr_set_data, sockaddr_get_data): New functions, replace the
|
||||||
|
old sockaddr_set_address, sockaddr_set_port, sockaddr_get_address,
|
||||||
|
and sockaddr_get_port.
