This directory constant is set in <b>configAll.h</b>. If the module name is provided to <b><i><a href="./straceLib.html#strace">strace</a></i>( )</b> then its output is sent to a file named <b>module-id.log</b> in the <b>STREAMS_STRACE_OUTPUT_DIR</b> directory.<p>These messages are obtained from the STREAMS log driver.If arguments are provided, they must be in triplets of the form <i>mid</i>,<i>sid</i>, and <i>level</i>, where <i>mid</i> is a STREAMS module ID number, <i>sid</i> is a sub-ID number, and <i>level</i> is a tracing priority level. Each triplet indicates that tracing messages are to be received from the specified module/driver, sub-ID (usually indicating minor device), and priority level equal to or less than the specified level. The token <i>all</i> can be used for any member to indicate no restriction for that attribute. <p>For additional information, see the<i>WindNet STREAMS for Tornado Component Release Supplement. </i><p></blockquote><h4>RETURNS</h4><blockquote><p>N/A<p><i>WindNet STREAMS for Tornado Component Release Supplement. </i></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./straceLib.html#top">straceLib</a></b><hr><a name="straceStop"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>straceStop</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>straceStop</i>( )</strong> - stop the <b><i><a href="./straceLib.html#strace">strace</a></i>( )</b> task (STREAMS Option)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>void straceStop ( void )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine deletes the <b><i><a href="./straceLib.html#strace">strace</a></i>( )</b> task from the system and performs a cleanupoperation.
