GETRPCENT(3)GETRPCENT(3)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 ()
DESCRIPTIONgetrpcent(), 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 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.
