Name
       hesiod - C Language Hesiod name server Interface Library

Syntax
       #include <hesiod.h>

       char **hes_resolve(name, HesiodNameType)
       char *name, *HesiodNameType;

       int hes_error( )

Description
       The  library  is  the  primary  interface  to the Hesiod name server.  The library routine takes two arguments, a name to be resolved and a
       string, known as a It returns a NULL terminated vector of strings for each resource record containing Hesiod data, or NULL if there is  any
       error.

NAME

       hesiod_getservbyname, hesiod_free_servent - Hesiod functions for retrieving service information

SYNOPSIS

       #include <hesiod.h>

       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

DESCRIPTION

       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
       matches proto.

RETURN VALUES

       On failure, hesiod_getservbyname returns NULL and sets the global variable errno to indicate the error.

ERRORS

       hesiod_getservbyname may fail for any of the reasons the routine hesiod_resolve may fail.
