HESIOD.CONF(5) File Formats Manual HESIOD.CONF(5)NAME
hesiod.conf - Configuration file for the Hesiod library
The file hesiod.conf determines the behavior of the Hesiod library. Blank lines and lines beginning with a `#' character are ignored. All
other lines should be of the form variable = value, where the value should be a single word. Possible variables and values are:
lhs Specifies the domain prefix used for Hesiod queries. In almost all cases, you should specify ``lhs=.ns''. The default value if you
do not specify an lhs value is no domain prefix, which is not compatible with most Hesiod domains.
rhs Specifies the default Hesiod domain; this value may be overridden by the HES_DOMAIN environment variable. You must specify an rhs
line for the Hesiod library to work properly.
Specifies which DNS classes Hesiod should do lookups in. Possible values are IN (the preferred class) and HS (the deprecated class,
still used by some sites). You may specify both classes separated by a comma to try one class first and then the other if no entry
is available in the first class. The default value of the classes variable is ``IN,HS''.
SEE ALSO hesiod(3)BUGS
There default value for ``lhs'' should probably be more reasonable.

HESIOD(3) Library Functions Manual HESIOD(3)NAME
hesiod_getservbyname, hesiod_free_servent - Hesiod functions for retrieving service information
struct servent *hesiod_getservbyname(void *context,
const char *name, const char *proto)
void hesiod_free_servent(void *context, struct servent *serv)
cc file.c -lhesiod
This family of functions allows you to retrieve service to port mappings using Hesiod. To perform lookups, you need an initialized Hesiod
context; see hesiod(3) for details. Information is returned in the same format as by getservbyname. It is the caller's responsibility to
call hesiod_free_servent with the returned service entry to free the resources used by the service entry.
Hesiod queries for service information are made using the ``service'' Hesiod type, using the service name as the Hesiod name. The corre-
sponding records should be space-separated lists of strings giving the service name, protocol, port number (in decimal), and zero or more
aliases for the service. There may be multiple records per service name; hesiod_getservbyname will pick the first one whose protocol
On failure, hesiod_getservbyname returns NULL and sets the global variable errno to indicate the error.
hesiod_getservbyname may fail for any of the reasons the routine hesiod_resolve may fail.
