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 ()
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 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.
FILES /etc/rpc
