following structure containing the broken-out
|

fields of an entry in the RPC program number data base.

<DL COMPACT>

The name of the server for this RPC program.

<DT id="3"><I>r_aliases</I>
|
|

|
|
A NULL-terminated list of alternate names for the RPC program.

The
|
|
<B>getrpcent</B>()
|
|
|
|
function reads the next entry from the database.
|
|
A connection is opened to the database if necessary.
|
|
<P>
|
|
|
|
The
|
|
<B>setrpcent</B>()
|
|
|
|
function opens a connection to the database,
|
|
and sets the next entry to the first entry.
|
|
If
|
|
<I>stayopen</I>
|
|
|
|
is nonzero,
|
|
then the connection to the database
|
|
will not be closed between calls to one of the
|
|
<B>getrpc*</B>()
|
|
|
|
functions.
|
|
<P>
|
|
|
|
The
|
|
<B>endrpcent</B>()
|
|
|
|
function closes the connection to the database.

|
<B>getrpcbyname</B>()

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.
