Telegrams are the largest packets that can be sent between nodes by the distributed objects product; their size is limited by the MTU size of theunderlying communications. If a distributed objects message exceeds the space allocated in a telegram for message data, that message is divided into multiple telegrams that are sent out in sequence. <p></blockquote><h4>AVAILABILITY</h4><blockquote><p>This module is distributed as a component of the unbundled distributedmessage queues option, VxFusion.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>distTBufLib.h</b><hr><a name="distTBufAlloc"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>distTBufAlloc( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>distTBufAlloc( )</strong> - allocate a telegram buffer from the pool of buffers (VxFusion option)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>DIST_TBUF * distTBufAlloc (void)</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine allocates a telegram buffer from a pre-allocated poolof telegram buffers.<p>It is the responsibility of the caller to use the <b><a href="./distTBufLib.html#distTBufFree">distTBufFree</a>( )</b> routine tofree the buffer when the caller is finished with it.<p></blockquote><h4>AVAILABILITY</h4><blockquote><p>This routine is distributed as a component of the unbundled distributedmessage queues option, VxFusion.<p></blockquote><h4>RETURNS</h4><blockquote><p>A pointer to a <b>DIST_TBUF</b>, or NULL if the allocation fails.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./distTBufLib.html#top">distTBufLib</a></b>, <b>distTBufFree</b><hr><a name="distTBufFree"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>distTBufFree( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>distTBufFree( )</strong> - return a telegram buffer to the pool of buffers (VxFusion option)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>void distTBufFree ( DIST_TBUF * pTBuf /* ptr to buffer to be returned to pool */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine returns a buffer previously allocated to a caller back tothe pool of free telegram buffers.<p></blockquote><h4>AVAILABILITY</h4><blockquote><p>This routine is distributed as a component of the unbundled distributedmessage queues option, VxFusion.<p></blockquote><h4>RETURNS</h4><blockquote><p>N/A<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./distTBufLib.html#top">distTBufLib</a></b>, <b>distTBufAlloc</b></body></html>⌨️ 快捷键说明
