SYNOPSIS


dt-gethost [options] name

DESCRIPTION


This 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).
