Such messages are delivered to the task or thread sample port set by 30*c54f35caSApple OSS Distributions<strong>task_sample</strong> or <strong>thread_sample</strong>. The <strong>prof_server</strong> 31*c54f35caSApple OSS Distributionsfunction performs all 32*c54f35caSApple OSS Distributionsnecessary argument handling for this kernel message and calls the appropriate 33*c54f35caSApple OSS Distributionshandling function. These functions must be supplied by the caller. 34*c54f35caSApple OSS Distributions<h3>RETURN VALUES</h3> 35*c54f35caSApple OSS Distributions<dl> 36*c54f35caSApple OSS Distributions<p> 37*c54f35caSApple OSS Distributions<dt> <strong>TRUE</strong> 38*c54f35caSApple OSS Distributions<dd> 39*c54f35caSApple OSS DistributionsThe message was handled and the appropriate function was called. 40*c54f35caSApple OSS Distributions<p> 41*c54f35caSApple OSS Distributions<dt> <strong>FALSE</strong> 42*c54f35caSApple OSS Distributions<dd> 43*c54f35caSApple OSS DistributionsThe message did not apply to the sample mechanism and no other 44*c54f35caSApple OSS Distributionsaction was taken. 45*c54f35caSApple OSS Distributions</dl> 46*c54f35caSApple OSS Distributions<h3>RELATED INFORMATION</h3> 47*c54f35caSApple OSS Distributions<p> 48*c54f35caSApple OSS DistributionsFunctions: 49*c54f35caSApple OSS Distributions<a href="receive_samples.html"><strong>receive_samples<strong></a>. 50
