Such 30*0f4c859eSApple OSS Distributionsmessages were sent in response to the various 31*0f4c859eSApple OSS Distributions<strong>device_</strong>...<strong>_request</strong>... 32*0f4c859eSApple OSS Distributionscalls. It is assumed when using 33*0f4c859eSApple OSS Distributionsthose calls that some task is listening for reply messages on the port named as a 34*0f4c859eSApple OSS Distributionsreply port to those calls. The <strong>device_reply_server</strong> 35*0f4c859eSApple OSS Distributionsfunction performs all 36*0f4c859eSApple OSS Distributionsnecessary argument handling for a kernel message and calls one 37*0f4c859eSApple OSS Distributionsof the device server functions to interpret the message. 38*0f4c859eSApple OSS Distributions<h3>RETURN VALUES</h3> 39*0f4c859eSApple OSS Distributions<dl> 40*0f4c859eSApple OSS Distributions<p> 41*0f4c859eSApple OSS Distributions<dt> <strong>TRUE</strong> 42*0f4c859eSApple OSS Distributions<dd> 43*0f4c859eSApple OSS DistributionsThe message was handled and the appropriate function was called. 44*0f4c859eSApple OSS Distributions<p> 45*0f4c859eSApple OSS Distributions<dt> <strong>FALSE</strong> 46*0f4c859eSApple OSS Distributions<dd> 47*0f4c859eSApple OSS DistributionsThe message did not apply to this device handler interface and no other 48*0f4c859eSApple OSS Distributionsaction was taken. 49*0f4c859eSApple OSS Distributions</dl> 50*0f4c859eSApple OSS Distributions<h3>RELATED INFORMATION</h3> 51*0f4c859eSApple OSS Distributions<p> 52*0f4c859eSApple OSS DistributionsFunctions: 53*0f4c859eSApple OSS Distributions<a href="device_open.html"><strong>ds_device_open_reply<strong></a>, 54*0f4c859eSApple OSS Distributions<a href="device_write.html"><strong>ds_device_write_reply<strong></a>, 55*0f4c859eSApple OSS Distributions<a href="device_write_inband.html"><strong>ds_device_write_reply_inband<strong></a>, 56*0f4c859eSApple OSS Distributions<a href="device_read.html"><strong>ds_device_read_reply<strong></a>, 57*0f4c859eSApple OSS Distributions<a href="device_read_inband.html"><strong>ds_device_read_reply_inband<strong></a>, 58*0f4c859eSApple OSS Distributions<a href="device_read_overwrite.html"><strong>ds_device_read_reply_overwrite<strong></a>. 59
