GETRPCENT(3N)

NAME
endrpcent, getrpcbyname, getrpcbynumber, getrpcent, setrpcent - get rpc entry

SYNOPSIS
#include <netdb.h>

endrpcent()

struct rpcent *getrpcbyname(name)
char *name;

struct rpcent *getrpcbynumber(number)
int number;

struct rpcent *getrpcent()

setrpcent(stayopen)
int stayopen;

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 alternate 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 EOF is encountered.

FILES
/etc/rpc
/etc/yp/domainname/rpc.bynumber

DIAGNOSTICS
Null pointer (0) returned on EOF or error.
