Such 30*e13b1fa5SApple OSS Distributionsmessages were sent in response to the various 31*e13b1fa5SApple OSS Distributions<strong>device_</strong>...<strong>_request</strong>... 32*e13b1fa5SApple OSS Distributionscalls. It is assumed when using 33*e13b1fa5SApple OSS Distributionsthose calls that some task is listening for reply messages on the port named as a 34*e13b1fa5SApple OSS Distributionsreply port to those calls. The <strong>device_reply_server</strong> 35*e13b1fa5SApple OSS Distributionsfunction performs all 36*e13b1fa5SApple OSS Distributionsnecessary argument handling for a kernel message and calls one 37*e13b1fa5SApple OSS Distributionsof the device server functions to interpret the message. 38*e13b1fa5SApple OSS Distributions<h3>RETURN VALUES</h3> 39*e13b1fa5SApple OSS Distributions<dl> 40*e13b1fa5SApple OSS Distributions<p> 41*e13b1fa5SApple OSS Distributions<dt> <strong>TRUE</strong> 42*e13b1fa5SApple OSS Distributions<dd> 43*e13b1fa5SApple OSS DistributionsThe message was handled and the appropriate function was called. 44*e13b1fa5SApple OSS Distributions<p> 45*e13b1fa5SApple OSS Distributions<dt> <strong>FALSE</strong> 46*e13b1fa5SApple OSS Distributions<dd> 47*e13b1fa5SApple OSS DistributionsThe message did not apply to this device handler interface and no other 48*e13b1fa5SApple OSS Distributionsaction was taken. 49*e13b1fa5SApple OSS Distributions</dl> 50*e13b1fa5SApple OSS Distributions<h3>RELATED INFORMATION</h3> 51*e13b1fa5SApple OSS Distributions<p> 52*e13b1fa5SApple OSS DistributionsFunctions: 53*e13b1fa5SApple OSS Distributions<a href="device_open.html"><strong>ds_device_open_reply<strong></a>, 54*e13b1fa5SApple OSS Distributions<a href="device_write.html"><strong>ds_device_write_reply<strong></a>, 55*e13b1fa5SApple OSS Distributions<a href="device_write_inband.html"><strong>ds_device_write_reply_inband<strong></a>, 56*e13b1fa5SApple OSS Distributions<a href="device_read.html"><strong>ds_device_read_reply<strong></a>, 57*e13b1fa5SApple OSS Distributions<a href="device_read_inband.html"><strong>ds_device_read_reply_inband<strong></a>, 58*e13b1fa5SApple OSS Distributions<a href="device_read_overwrite.html"><strong>ds_device_read_reply_overwrite<strong></a>. 59
