PURPOSE

Gets an RPC entry.

SYNTAX


#include <netdb.h>

struct rpcent *getrpcent()

struct rpcent *getrpcbyname(name)
char *name;

struct rpcent *getrpcbynumber(number)
int number;

setrpcent(stayopen)
int stayoen

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.

getrpcent() opens and rewinds the file.  If the stayopen flag is nonzero, 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.

Notes:

  1. A NULL pointer is returned on EOF or error.

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