Such messages are delivered to the task or thread sample port set by \r<strong>task_sample</strong> or <strong>thread_sample</strong>. The <strong>prof_server</strong>\rfunction performs all\rnecessary argument handling for this kernel message and calls the appropriate\rhandling function. These functions must be supplied by the caller.\r<h3>RETURN VALUES</h3>\r<dl>\r<p>\r<dt> <strong>TRUE</strong>\r<dd>\rThe message was handled and the appropriate function was called.\r<p>\r<dt> <strong>FALSE</strong>\r<dd>\rThe message did not apply to the sample mechanism and no other\raction was taken.\r</dl>\r<h3>RELATED INFORMATION</h3>\r<p>\rFunctions:\r<a href="receive_samples.html"><strong>receive_samples<strong></a>.\r |
