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:
r_name | The name of the server for this RPC program. |
r_aliases | A NULL-terminated list of alternate names for the RPC program. |
r_number | 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
