The kernel makes this call to allow the memory 47*2c2f96dcSApple OSS Distributionsmanager to clean 48*2c2f96dcSApple OSS Distributionsup data structures associated with the deallocated mappings. 49*2c2f96dcSApple OSS DistributionsThe call provides 50*2c2f96dcSApple OSS Distributionsreceive rights to the memory cache control port so that the memory manager 51*2c2f96dcSApple OSS Distributionscan retrieve any messages it sent into this port before knowing the memory 52*2c2f96dcSApple OSS Distributionsobject was being terminated and then destroy the port. The kernel also 53*2c2f96dcSApple OSS Distributionsrelinquishes its rights for all memory object ports. 54*2c2f96dcSApple OSS Distributions<p> 55*2c2f96dcSApple OSS DistributionsThe kernel terminates a memory object only after all address space mappings of 56*2c2f96dcSApple OSS Distributionsthe object have been deallocated, or upon explicit request by the memory 57*2c2f96dcSApple OSS Distributionsmanager. 58*2c2f96dcSApple OSS Distributions<h3>RETURN VALUES</h3> 59*2c2f96dcSApple OSS Distributions<p> 60*2c2f96dcSApple OSS DistributionsOnly generic errors apply. 61*2c2f96dcSApple OSS Distributions<h3>RELATED INFORMATION</h3> 62*2c2f96dcSApple OSS Distributions<p> 63*2c2f96dcSApple OSS DistributionsFunctions: 64*2c2f96dcSApple OSS Distributions<a href="memory_object_destroy.html"><strong>memory_object_destroy</strong></a>, 65*2c2f96dcSApple OSS Distributions<a href="mach_port_deallocate.html"><strong>mach_port_deallocate</strong></a>, 66*2c2f96dcSApple OSS Distributions<a href="memory_object_server.html"><strong>memory_object_server</strong></a>, 67*2c2f96dcSApple OSS Distributions<a href="SMO_server.html"><strong>seqnos_memory_object_server</strong></a>. 68
