       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

       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 encountered.
