<p>The Retrieve Device Capabilities (QTARDCAP) API retrieves information that
|
|
is associated with a specified tape device description or tape resource name.
|
|
The resource that is specified or associated with the specified device
|
|
description must currently exist on the system.</p>
|
|
|
|
<p>The QTARDCAP API currently supports the following device types:</p>
|
|
|
|
<ul>
|
|
<li>Tape (TAP) devices</li>
|
|
|
|
<li>Tape media library (TAPMLB) devices</li>
