The kernel makes this call to allow the memory 47*1031c584SApple OSS Distributionsmanager to clean 48*1031c584SApple OSS Distributionsup data structures associated with the deallocated mappings. 49*1031c584SApple OSS DistributionsThe call provides 50*1031c584SApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*1031c584SApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*1031c584SApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*1031c584SApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*1031c584SApple OSS Distributions<p> 55*1031c584SApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*1031c584SApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*1031c584SApple OSS Distributionsmanager. 58*1031c584SApple OSS Distributions<h3>RETURN VALUES</h3> 59*1031c584SApple OSS Distributions<p> 60*1031c584SApple OSS DistributionsOnly generic errors apply. 61*1031c584SApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*1031c584SApple OSS Distributions<p> 63*1031c584SApple OSS DistributionsFunctions: 64*1031c584SApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*1031c584SApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*1031c584SApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*1031c584SApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
