       getrpcent, getrpcbyname, getrpcbynumber - get RPC entry


       #include <netdb.h>

       struct rpcent *getrpcent()

       struct rpcent *getrpcbyname(name)
       char *name;

       struct rpcent *getrpcbynumber(number)
       int number;

       setrpcent (stayopen)
       int stayopen

       endrpcent ()


       getrpcent(),  getrpcbyname(), and getrpcbynumber() each return a pointer to an object with
       the following structure containing the broken-out fields of a  line  in  the  rpc  program
       number data base, /etc/rpc.

              struct    rpcent {
                   char *r_name;  /* name of server for this rpc program */
                   char **r_aliases;   /* alias list */
                   long r_number; /* rpc program number */

       The members of this structure are:
              r_name              The name of the server for this rpc program.
              r_aliases           A zero terminated list of alternate names for the rpc program.
              r_number            The rpc program number for this service.

       getrpcent() reads the next line of the file, opening the file if necessary.

       getrpcent()  opens  and  rewinds the file.  If the stayopen flag is non-zero, the net data
       base will not be closed after each call to getrpcent()  (either  directly,  or  indirectly
       through one of the other “getrpc” calls).

       endrpcent closes the file.

       getrpcbyname()  and  getrpcbynumber()  sequentially  search from the beginning of the file
       until a matching rpc program name or program number is  found,  or  until  end-of-file  is

       A NULL pointer is returned on EOF or error.
