dt-getaddr1
Command-line test program for the val_getaddrinfo() function
Usage
dt-getaddr {[options]
<hostname | IPv4
address | IPv6
address>}
Overview
This utility is a command-line wrapper around the val_getaddrinfo() function. It invokes the val_getaddrinfo() operation for the given command-line arguments and displays the return code from the function and the contents of the addrinfo structure.
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. If no validation is performed, or the result is neither trusted nor validated, a value of 0 is returned. The trusted and validated status values are obtained using the val_istrusted() and val_isvalidated() functions from libval(3).
