13 This utility is a command-line wrapper around the val_gethostbyname()
14 (and related) functions. It invokes the val_gethostbyname(),
15 val_gethostbyname_r() and val_gethostbyname2() functions for the given
16 command-line arguments and displays the returned hostent, the
17 validation status value, and the value of the h_errno variable.
18
19 The exit status for this program is 1 if the answer received is
20 trusted, 2 if the answer received is validated, and -1 for an error.
21 The program returns 0 if no validation was performed or if the result
22 was neither trusted nor validated. The trusted and validated status
23 values are obtained using the val_istrusted() and val_isvalidated()
24 functions from libval(3).
