get RPC entry
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <rpc/rpc.h>
struct rpcent *
getrpcent(
void);
struct rpcent *
getrpcbyname(
const
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 alternative 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 non-zero, 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.
FILES

NULL
pointer is returned on

All information is contained in a static area so it must be copied if it is to
