    .SH DESCRIPTION
    
    .B memory_object_get_attributes
    retrieves the current attributes
    associated with the memory object.  
    
    .SH ARGUMENTS
    .TP 15
    .B
    memory_control
    The port, provided by the kernel 
    in a 
    .B memory_object_init
    call, to which cache management requests may be issued.
    .TP 15
    .B
    object_ready
    When set, the kernel may issue new data and unlock requests on the
    associated memory object.
    .TP 15
    .B
    may_cache_object
    If set, the kernel may keep data 
    associated with this
    memory object, even after virtual memory references to it are gone.
    .TP 15
    .B
    copy_strategy
    How the kernel should copy regions of the associated
    memory object.
    
    .SH DIAGNOSTICS
   .TP 25
   KERN_SUCCESS
   This routine does not receive a reply message (and consequently
   has no return value), so only message transmission errors apply.
   
   .SH SEE ALSO
   .B memory_object_set_attributes, memory_object_copy
