NAME
getrpcent, getrpcbyname, getrpcbynumber, setrpcent, endrpcent - 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 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.
setrpcent() 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.
RETURN VALUE
A NULL pointer is returned on EOF or error.
FILES
