получить запись RPC (get RPC entry)
Имя (Name)
getrpcent, getrpcbyname, getrpcbynumber, setrpcent, endrpcent -
get RPC entry
Синопсис (Synopsis)
#include <netdb.h>
struct rpcent *getrpcent(void);
struct rpcent *getrpcbyname(const char *name);
struct rpcent *getrpcbynumber(int number);
void setrpcent(int stayopen);
void endrpcent(void);
Описание (Description)
The getrpcent(), getrpcbyname(), and getrpcbynumber() functions
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.
The getrpcent() function reads the next entry from the database.
A connection is opened to the database if necessary.
The setrpcent() function opens a connection to the database, and
sets the next entry to the first entry. If stayopen is nonzero,
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.
The getrpcbyname() and getrpcbynumber() functions 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.
Возвращаемое значение (Return value)
On success, getrpcent(), getrpcbyname(), and getrpcbynumber()
return a pointer to a statically allocated rpcent structure.
NULL is returned on EOF or error.
Файлы (Files)
/etc/rpc
RPC program number database.
