NAME
getrpcent, getrpcbyname, getrpcbynumber, setrpcent, endrpcent - get
RPC entry
LIBRARY
Standard C library
( libc,~ -lc)
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);
DESCRIPTION
The
getrpcent(),
getrpcbyname(),
and
getrpcbynumber()
functions each return a pointer to an object with the
following structure containing the broke-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 NUL-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 en-o-file is encountered.
RETURN VALUE
On success,
getrpcent(),
getrpcbyname(),
and
getrpcbynumber()
return a pointer to a statically allocated
rpcent
structure.
NULL is returned on EOF or error.
FILES
- /etc/rpc
-
RPC program number database.
