GETRPCENT(3) BSD Library Functions Manual GETRPCENT(3)
NAME
getrpcent, getrpcbyname, getrpcbynumber, endrpcent, setrpcent -- get RPC entry
SYNOPSIS
#include <netdb.h>
struct rpcent *
getrpcent(void);
struct rpcent *
getrpcbyname(char *name);
struct rpcent *
getrpcbynumber(int number);
void
setrpcent(int stayopen);
void
endrpcent(void);
DESCRIPTION
getrpcent(), getrpcbyname(), and getrpcbynumber(), each return a pointer to an object with the follow-ing following
ing 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.
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 end-of-file is encountered.
FILES
