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 neces-
       sary.

       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 getrp-
       cent() (either  directly,  or  indirectly  through  one  of  the  other
       "getrpc" calls).

       endrpcent closes the file.

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

FILES
       /etc/rpc

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.
