|
|
<p>dp_recv allows one to bypass the Tcl I/O layer and call the
|
|
channel's receive method directly. There are several problems
|
|
with Tcl's I/O system because it buffers data internally and it
|
|
is line or file-based.</p>
|
|
|
|
<p>dp_recv calls the channel's receive method <strong>once</strong>
|
|
and returns the received data.</p>
|
|
|
|
<p><strong>Examples</strong></p>
