If the .Fa stayopen flag is non-zero, the net data base will not be closed after each call to .Fn getrpcent (either directly, or indirectly through one of the other .Dq getrpc calls). .Pp .Fn endrpcent closes the file. .Pp .Fn getrpcbyname and .Fn 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. .Sh FILES .Pa /etc/rpc .Sh SEE ALSO .Xr rpc 5 , .Xr rpcinfo 8 , .Xr ypserv 8 .Sh DIAGNOSTICS A .Dv NULL pointer is returned on .Dv EOF or error. .Sh BUGS All information is contained in a static area so it must be copied if it is to be saved.
