The kernel makes this call to allow the memory 47*699cd480SApple OSS Distributionsmanager to clean 48*699cd480SApple OSS Distributionsup data structures associated with the deallocated mappings. 49*699cd480SApple OSS DistributionsThe call provides 50*699cd480SApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*699cd480SApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*699cd480SApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*699cd480SApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*699cd480SApple OSS Distributions<p> 55*699cd480SApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*699cd480SApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*699cd480SApple OSS Distributionsmanager. 58*699cd480SApple OSS Distributions<h3>RETURN VALUES</h3> 59*699cd480SApple OSS Distributions<p> 60*699cd480SApple OSS DistributionsOnly generic errors apply. 61*699cd480SApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*699cd480SApple OSS Distributions<p> 63*699cd480SApple OSS DistributionsFunctions: 64*699cd480SApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*699cd480SApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*699cd480SApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*699cd480SApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
