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(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 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.
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.
