|
Tcl error with a system message. The arguments are:
|
|
<ul>
|
|
<li>
|

<b>machid </b>is the machine ID of the machine that <i>sent</i> this
|
|
message.</li>
|
|
|
|
<li>
|
|
<b>control</b> is a binary string containing the exact contents of the
|
|
<b><i>control</i></b> argument to the <b><i>sendproc</i></b> function
|
|
that was passed this message on another site.</li>
|
|
|
|
<li>
|
|
<b>rec</b> is a binary string containing the exact contents of the
|
|
<b><i>rec</i></b> argument to the <b><i>sendproc</i></b> function

|
<p>This command causes a replication election. It is a direct translation
|
|
of the <a href="../../docs/api_c/rep_elect.html">rep_elect</a> function.
|
|
Its arguments, all integers, correspond exactly to that C function's
|
|
parameters.
|
|
It will return a list containing two integers, which contain,
|
|
respectively, the integer values returned in the C function's
|
|
<i><b>midp</b></i> and <i><b>selfp</b></i> parameters.
