38*33de042dSApple OSS Distributions<h3>DESCRIPTION</h3>
39*33de042dSApple OSS Distributions<p>
40*33de042dSApple OSS DistributionsA <strong>default_pager_info</strong> function is called as the result
41*33de042dSApple OSS Distributionsof a message requesting
42*33de042dSApple OSS Distributionsthat the default memory manager return information concerning the default
43*33de042dSApple OSS Distributionspager's paging partitions.  The kernel does not make this call
44*33de042dSApple OSS Distributionsitself (which is why it
45*33de042dSApple OSS Distributionscan be a synchronous call); this request is only issued by (privileged) tasks
46*33de042dSApple OSS Distributionsholding the default memory manager port.
47*33de042dSApple OSS Distributions<h3>RETURN VALUES</h3>
48*33de042dSApple OSS Distributions<p>
49*33de042dSApple OSS DistributionsOnly generic errors apply.
