GETRPCENT(3)                                                      GETRPCENT(3)



NAME
       getrpcent, getrpcbyname, getrpcbynumber - get RPC entry

SYNOPSIS
       #include <netdb.h>

       struct rpcent *getrpcent()

       struct rpcent *getrpcbyname(name)
       char *name;

       struct rpcent *getrpcbynumber(number)
       int number;

       setrpcent (stayopen)
       int stayopen;

       endrpcent ()

DESCRIPTION
       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.

       setrpcent() 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 encountered.

FILES
       /etc/rpc

SEE ALSO
       rpc(5), rpcinfo(8), ypserv(8)

DIAGNOSTICS
       A NULL pointer is returned on EOF or error.

BUGS
       All information is contained in a static area so it must be copied if it is  to  be
       saved.
