The kernel makes this call to allow the memory 47*33de042dSApple OSS Distributionsmanager to clean 48*33de042dSApple OSS Distributionsup data structures associated with the deallocated mappings. 49*33de042dSApple OSS DistributionsThe call provides 50*33de042dSApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*33de042dSApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*33de042dSApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*33de042dSApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*33de042dSApple OSS Distributions<p> 55*33de042dSApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*33de042dSApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*33de042dSApple OSS Distributionsmanager. 58*33de042dSApple OSS Distributions<h3>RETURN VALUES</h3> 59*33de042dSApple OSS Distributions<p> 60*33de042dSApple OSS DistributionsOnly generic errors apply. 61*33de042dSApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*33de042dSApple OSS Distributions<p> 63*33de042dSApple OSS DistributionsFunctions: 64*33de042dSApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*33de042dSApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*33de042dSApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*33de042dSApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
