\r</pre>
\r<h3>FIELDS</h3>
\r<dl>
\r<dt> <var>mps_pset</var>
\r<dd>
\rContaining port set.
\r <p>
\r<dt> <var>mps_seqno</var>
\r<dd>
\rCurrent sequence number for the port.
\r <p>
\r <dt> <var>mps_mscount</var>
\r <dd>
\r Make-send count.
\r <p>
\r<dt> <var>mps_msgcount</var>
\r<dd>
\rUpper limit for the number of messages that may be queued to the port
\r before the system blocks send operations.
\r <p>
\r <dt> <var>mps_msgcount</var>
\r<dd>
\r Number of messages currently queued on the port.
\r <p>
\r<dt> <var>mps_sorights</var>
\r<dd>
\rHow many send-once rights.
\r <p>
\r<dt> <var>mps_srights</var>
\r<dd>
\rSpecifies whether or not send rights exist. Valid values are as follows:
\r <dl>
\r <p>
\r <dt> MPS_FALSE
\r <dd>
\r No send rights currently in existence.
\r <p>
\r <dt> MPS_TRUE
\r <dd>
\r Send rights exist and no-more-senders notification is enabled.
\r <p>
\r <dt> MPS_UNKNOWN
\r <dd>
\r The port does not permit no-more-senders notification requests;
\r consequently, the system does not know whether or not send rights
\r exist.
\r </dl>
\r <p>
\r<dt> <var>mps_pdrequest</var>
\r<dd>
\r Specifies whether or not a port-deleted notification has been requested.
\r <p>
\r<dt> <var>mps_nsrequest</var>
\r<dd>
\rTrue if no-senders requested.
\r <p>
\r<dt> <var>mps_flags</var>
\r<dd>
\r Flags associated with the port.
\r</dl>
\r<h3>DESCRIPTION</h3>
\r<p>
\rThe <strong>mach_port_status</strong> structure is used to provide
\rinformation about a port in response to an invocation of the
\r<strong>mach_port_get_attributes</strong> interface.
\r<h3>NOTES</h3>
\r<p>
\rThis structure is machine word length sensitive due
\rto the presence of the port
\rset name.
