19/* Some functions are used by the stub resolver implementation
20 internally and thus have to be located in libc. They have been
21 historially exported for application use as well. However, the
22 stub resolver dependency on those functions is not intrinsic to
23 what the stub resolver does, and it is possible that a future
24 version of the stub resolver will not need them anymore. The
25 public symbols for these functions remain in libresolv, and are not
26 moved to libc, to avoid adding new symbol versions for legacy
27 functions. */
