GETRPCENT(3) Linux Programmer's Manual GETRPCENT(3)

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 an entry in the RPC program number data base.

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:

The name of the server for this RPC program.
A NULL-terminated list of alternate names for the RPC program.
The RPC program number for this service.

getrpcent() reads the next entry from the database. A connection is opened to the database if necessary.

setrpcent() function opens a connection to the database, and sets the next entry to the first entry. If stayopen is non-zero, then the connection to the database will not be closed between calls to one of the getrpc*() functions.

The endrpcent() function closes the connection to the database.

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

On success, getrpcent(), getrpcbyname(), and getrpcbynumber() return a pointer to a statically allocated rpcent structure. A NULL pointer is returned on EOF or error.

FILES

/etc/rpc
RPC program number database.
