  14   14  
  15   15  PARAMETERS
  16   16       vmp     The vmem arena to which the span should be added.
  17   17  
  18   18       vaddr   The base address of the span to add.
  19   19  
  20      -     size    The size of the span to add
       20 +     size    The size of the span to add.
  21   21  
  22   22       vmflag  Flags affecting the allocation of the span to add.
  23   23  
  24   24  DESCRIPTION
  25   25       The vmem_add() function adds size bytes starting at vaddr to a vmem arena
  26   26       from which future calls to vmem_alloc() may allocate.
  27   27  
  28      -     VM_SLEEP or VM_NOSLEEP must be specified, and indicate whether the
  29      -     addition may block.
       28 +     VM_SLEEP or VM_NOSLEEP must be specified in vmflag, and indicate whether
       29 +     the addition may block.

  31   31  CONTEXT
  32   32       This function can be called from either user or kernel context.  If the
  33   33       VM_NOSLEEP flag is specified, it may also be called from interrupt
  34   34       context.
  35   35  
  36   36  RETURN VALUES
  37   37       Upon success vmem_add() returns vaddr.  On failure, NULL is returned.
