The kernel makes this call to allow the memory 47*0f4c859eSApple OSS Distributionsmanager to clean 48*0f4c859eSApple OSS Distributionsup data structures associated with the deallocated mappings. 49*0f4c859eSApple OSS DistributionsThe call provides 50*0f4c859eSApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*0f4c859eSApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*0f4c859eSApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*0f4c859eSApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*0f4c859eSApple OSS Distributions<p> 55*0f4c859eSApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*0f4c859eSApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*0f4c859eSApple OSS Distributionsmanager. 58*0f4c859eSApple OSS Distributions<h3>RETURN VALUES</h3> 59*0f4c859eSApple OSS Distributions<p> 60*0f4c859eSApple OSS DistributionsOnly generic errors apply. 61*0f4c859eSApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*0f4c859eSApple OSS Distributions<p> 63*0f4c859eSApple OSS DistributionsFunctions: 64*0f4c859eSApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*0f4c859eSApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*0f4c859eSApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*0f4c859eSApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
