This member represents the call-related features that may possibly be available on an address (static availability as opposed to dynamic availability). Invoking a supported feature requires the call to be in the proper state and the underlying line device to be opened in a compatible mode. A zero in a bit position indicates that the corresponding feature is never available. A one indicates that the corresponding feature may be available if the application has the right privileges to the call and the call is in the appropriate state for the operation to be meaningful.

Invoking a supported feature requires the address to be in the proper state and the underlying line device to be opened in a compatible mode. A zero in a bit position indicates that the corresponding feature is never available. A one indicates that the corresponding feature may be available if the address is in the appropriate state for the operation to be meaningful. This member allows an application to discover which address features can be (and which can never be) supported by the address. </DD>

<DT><B>dwPredictiveAutoTransferStates</B> </DT>

<DD>The call state or states upon which a call made by a predictive dialer can be set to automatically transfer the call to another address; one or more of the <A HREF="constnts_6t0z.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/constnts_6t0z.htm">LINECALLSTATE_ Constants</A>.

<H4>Remarks</H4>

<P>Device-specific extensions should use the <B>DevSpecific</B> (<B>dwDevSpecificSize</B> and <B>dwDevSpecificOffset</B>) variably sized area of this data structure. </P>

<P>Older applications are compiled without this member in the <B>LINEADDRESSCAPS</B> structure, and using a SIZEOF(LINEADDRESSCAPS) smaller than the new size. The application passes in a <I>dwAPIVersion</I> parameter with the <A HREF="func1_533n.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/func1_533n.htm"><B>lineGetAddressCaps</B></A> function, which can be used for guidance by TAPI in handling this situation. If the application passes in a <B>dwTotalSize</B> member less than the size of the fixed portion of the structure as defined in the <B>dwAPIVersion</B> member specified, LINEERR_STRUCTURETOOSMALL is returned. If sufficient memory has been allocated by the application, before calling <A HREF="javascript:if(confirm('http://msdn.microsoft.com/library/psdk/tspi21/func1_16k3.htm  \n\n這個文件不能通過 Teleport Pro 取回, 因為 地址在一個域或為它的開始地址設(shè)定的邊界的外部路徑上.  \n\n你想從服務(wù)器打開它嗎?'))window.location='http://msdn.microsoft.com/library/psdk/tspi21/func1_16k3.htm'" tppabs="http://msdn.microsoft.com/library/psdk/tspi21/func1_16k3.htm"><B>TSPI_lineGetAddressCaps</B></A>, TAPI sets the <B>dwNeededSize</B> and <B>dwUsedSize</B> members to the fixed size of the structure as it existed in the specified API version. </P>

<P>New service providers (that support the new API version) must examine the API version passed in. If the API version is less than the highest version supported by the provider, the service provider must not fill in fields not supported in older API versions, as these would fall in the variable portion of the older structure. </P>

<P>New applications must be cognizant of the API version negotiated, and not examine the contents of fields in the fixed portion beyond the original end of the fixed portion of the structure for the negotiated API version. </P>

<P>The members <B>dwPredictiveAutoTransferStates</B> through <B>dwAvailableMediaModes</B> are available only to applications that request an API version of 2.0 or later when calling <A HREF="func1_533n.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/func1_533n.htm"><B>lineGetAddressCaps</B></A>. </P>
