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);
DESCRIPTIONgetrpcent(), 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 nonzero, then the con‐
nection 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 begin‐
ning 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.
CONFORMING TO
Not in POSIX.1-2001. Present on the BSDs, Solaris, and many other sys‐
tems.
BUGS
All information is contained in a static area so it must be copied if
it is to be saved.
