GETRPCENT(NS) UNIX System V
Name
getrpcent, getrpcbyname, getrpcbynumber - Get RPC entry
Syntax
#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.
The commands operate as follows:
getrpcent reads the next line of the file, opening the file
if necessary.
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
beginning of the file until a matching RPC program name or
program number is found, or until EOF is encountered.
Files

All information is contained in a static area so it must be
