SYNOPSIS

#include <rpc/rpc.h>
struct rpcent * getrpcent (void);
struct rpcent * getrpcbyname (char *name);
struct rpcent * getrpcbynumber (int number);
void setrpcent (int stayopen);
void endrpcent (void);

DESCRIPTION

The getrpcent (,);
getrpcbyname (,);
and getrpcbynumber ();
functions 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.

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

The setrpcent ();
function opens and rewinds the file. If the Fa 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).

The endrpcent ();
function closes the file.

The getrpcbyname ();
and getrpcbynumber ();
functions 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.
