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.

structrpcent {
char∗r_name;/∗ name of server for this rpc program ∗/
char∗∗r_aliases;/∗ alias list ∗/
longr_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.
