The kernel makes this call to allow the memory 47*5c2921b0SApple OSS Distributionsmanager to clean 48*5c2921b0SApple OSS Distributionsup data structures associated with the deallocated mappings. 49*5c2921b0SApple OSS DistributionsThe call provides 50*5c2921b0SApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*5c2921b0SApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*5c2921b0SApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*5c2921b0SApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*5c2921b0SApple OSS Distributions<p> 55*5c2921b0SApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*5c2921b0SApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*5c2921b0SApple OSS Distributionsmanager. 58*5c2921b0SApple OSS Distributions<h3>RETURN VALUES</h3> 59*5c2921b0SApple OSS Distributions<p> 60*5c2921b0SApple OSS DistributionsOnly generic errors apply. 61*5c2921b0SApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*5c2921b0SApple OSS Distributions<p> 63*5c2921b0SApple OSS DistributionsFunctions: 64*5c2921b0SApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*5c2921b0SApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*5c2921b0SApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*5c2921b0SApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
