You cannot change the + address of an IPv6 nameserver dynamically in your program though. + + +Using the resolver in multi-threaded code +========================================= + +The traditional resolver interfaces `res_query', `res_search', +`res_mkquery', `res_send' and `res_init', used a static (global) +resolver state stored in the `_res' structure. Therefore, these +interfaces are not thread-safe. Therefore, BIND 8.2 introduced a set +of "new" interfaces `res_nquery', `res_nsearch', `res_nmkquery', +`res_nsend' and `res_ninit' that take a `res_state' as their first +argument, so you can use a per-thread resolver state. In glibc, when +you link with -lpthread, such a per-thread resolver state is already +present. It can be accessed using `_res', which has been redefined as +a macro, in a similar way to what has been done for the `errno' and +`h_errno' variables. This per-thread resolver state is also used for +the `gethostby*' family of functions, which means that for example +`gethostbyname_r' is now fully thread-safe and re-entrant. The +traditional resolver interfaces however, continue to use a single +resolver state and are therefore still thread-unsafe. The resolver +state is the same resolver state that is used for the initial ("main") +thread. + +This has the following consequences for existing binaries and source +code: + +* Single-threaded programs will continue to work. There should be no + user-visible changes when you recompile them. + +* Multi-threaded programs that use the traditional resolver interfaces + in the "main" thread should continue to work, except that they no + longer see any changes in the global resolver state caused by calls + to, for example, `gethostbyname' in other threads. Again there + should be no user-visible changes when you recompile these programs. + +* Multi-threaded programs that use the traditional resolver interfaces + in more than one thread should be just as buggy as before (there are + no problems if you use proper locking of course). If you recompile + these programs, manipulating the _res structure in threads other + than the "main" thread will seem to have no effect though. + +* In Multi-threaded that manipulate the _res structure, calls to + functions like `gethostbyname' in threads other than the "main" + thread won't be influenced by the those changes anymore. So if you + set RES_USE_INET6, a call to `gethostbyname' won't return any IPv6 + hosts anymore. If you recompile such programs, manipulating the + _res structure will affect the thread in which you do so instead of + the "main" thread. + +We recommend to use the new thread-safe interfaces in new code, since +the traditional interfaces have been deprecated by the BIND folks. +For compatibility with other (older) systems you might want to +continue to use those interfaces though. + + +Using the resolver in C++ code +============================== + +There resolver contains some hooks which will allow the user to +install some callback functions that make it possible to filter DNS +requests and responses.
