dt-gethost [options] name
DESCRIPTIONThis utility is a command-line wrapper around the val_gethostbyname() (and related) functions. It invokes the val_gethostbyname(), val_gethostbyname_r() and val_gethostbyname2() functions for the given command-line arguments and displays the returned hostent, the validation status value, and the value of the h_errno variable.
The exit status for this program is 1 if the answer received is trusted, 2 if the answer received is validated, and -1 for an error. The program returns 0 if no validation was performed or if the result was neither trusted nor validated. The trusted and validated status values are obtained using the val_istrusted() and val_isvalidated() functions from libval(3).
