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.

     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 begin-
     ning of the file until a matching rpc program name or program number is
     found, or until end-of-file is encountered.
