Print the message associated with the value of h_errno to standard error

- prefix
- NULL, or a string that you want to print before the
error message.

The herror() function prints
the message corresponding to the error number
contained in
h_errno
to
stderr.
The following functions can set h_errno:
If the prefix string is non-NULL, it's printed,
followed by a colon and a space. The error message is printed with a
trailing newline. One of the following messages could be printed:
- HOST_NOT_FOUND
- Authoritative answer: Unknown host.
- NETDB_INTERNAL
- You specified an invalid address family when calling
gethostbyname2().
- NO_DATA
- Valid name, no data record of the requested type.
The name is known to the name server, but has no IP
address associated with it—this isn't a temporary
error. Another type of request to the name server using this
domain name will result in an answer (e.g. a
mail-forwarder may be registered for this domain).
- NO_RECOVERY
- Unknown server error. An unexpected server failure was encountered.
This is a nonrecoverable network error.
- TRY_AGAIN
- Nonauthoritative answer: Host name lookup failure.
This is usually a temporary error and means that the
local server didn't receive a response from an authoritative
server. A retry at some later time may succeed.
