Such 30*c54f35caSApple OSS Distributionsmessages were sent in response to the various 31*c54f35caSApple OSS Distributions<strong>device_</strong>...<strong>_request</strong>... 32*c54f35caSApple OSS Distributionscalls. It is assumed when using 33*c54f35caSApple OSS Distributionsthose calls that some task is listening for reply messages on the port named as a 34*c54f35caSApple OSS Distributionsreply port to those calls. The <strong>device_reply_server</strong> 35*c54f35caSApple OSS Distributionsfunction performs all 36*c54f35caSApple OSS Distributionsnecessary argument handling for a kernel message and calls one 37*c54f35caSApple OSS Distributionsof the device server functions to interpret the message. 38*c54f35caSApple OSS Distributions<h3>RETURN VALUES</h3> 39*c54f35caSApple OSS Distributions<dl> 40*c54f35caSApple OSS Distributions<p> 41*c54f35caSApple OSS Distributions<dt> <strong>TRUE</strong> 42*c54f35caSApple OSS Distributions<dd> 43*c54f35caSApple OSS DistributionsThe message was handled and the appropriate function was called. 44*c54f35caSApple OSS Distributions<p> 45*c54f35caSApple OSS Distributions<dt> <strong>FALSE</strong> 46*c54f35caSApple OSS Distributions<dd> 47*c54f35caSApple OSS DistributionsThe message did not apply to this device handler interface and no other 48*c54f35caSApple OSS Distributionsaction was taken. 49*c54f35caSApple OSS Distributions</dl> 50*c54f35caSApple OSS Distributions<h3>RELATED INFORMATION</h3> 51*c54f35caSApple OSS Distributions<p> 52*c54f35caSApple OSS DistributionsFunctions: 53*c54f35caSApple OSS Distributions<a href="device_open.html"><strong>ds_device_open_reply<strong></a>, 54*c54f35caSApple OSS Distributions<a href="device_write.html"><strong>ds_device_write_reply<strong></a>, 55*c54f35caSApple OSS Distributions<a href="device_write_inband.html"><strong>ds_device_write_reply_inband<strong></a>, 56*c54f35caSApple OSS Distributions<a href="device_read.html"><strong>ds_device_read_reply<strong></a>, 57*c54f35caSApple OSS Distributions<a href="device_read_inband.html"><strong>ds_device_read_reply_inband<strong></a>, 58*c54f35caSApple OSS Distributions<a href="device_read_overwrite.html"><strong>ds_device_read_reply_overwrite<strong></a>. 59
