The kernel makes this call to allow the memory 47*c54f35caSApple OSS Distributionsmanager to clean 48*c54f35caSApple OSS Distributionsup data structures associated with the deallocated mappings. 49*c54f35caSApple OSS DistributionsThe call provides 50*c54f35caSApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*c54f35caSApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*c54f35caSApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*c54f35caSApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*c54f35caSApple OSS Distributions<p> 55*c54f35caSApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*c54f35caSApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*c54f35caSApple OSS Distributionsmanager. 58*c54f35caSApple OSS Distributions<h3>RETURN VALUES</h3> 59*c54f35caSApple OSS Distributions<p> 60*c54f35caSApple OSS DistributionsOnly generic errors apply. 61*c54f35caSApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*c54f35caSApple OSS Distributions<p> 63*c54f35caSApple OSS DistributionsFunctions: 64*c54f35caSApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*c54f35caSApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*c54f35caSApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*c54f35caSApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
