GETNODEADD(3)						     Library Functions Manual						     GETNODEADD(3)

NAME

       getnodeadd - DECnet address of executor node

SYNOPSIS

       #include <netdnet/dn.h>
       #include <netdnet/dnetdb.h>

       struct dn_naddr *getnodeadd (void)

DESCRIPTION

       getnodeadd searches the decnet hosts file for the executor node and returns the DECnet address in the dn_naddr structure
       If no entry is found, returns NULL

EXAMPLE

       #include <netdnet/dn.h>
       #include <netdnet/dnetdb.h>
       #include <sys/socket.h>

       main(void)
       {
	   struct dn_naddr	*binaddr;

	   if ( (binaddr=getnodeadd()) == NULL)
	       printf("Error, cannot find executor node address");
	   else
	       printf("getnodeadd successfully got executor node address");
       }

NAME

       dnet_addr - DECnet nodename to address translation

SYNOPSIS

       #include <netdnet/dn.h>

       struct dn_naddr *dnet_addr (char *nodename)

DESCRIPTION

       dnet_addr search the decnet hosts file for nodename and returns the DECnet address in the dn_naddr structure
       If no entry is found, returns NULL
