       func    The function to apply to each segment matching typemask.  func
!              should be of 3 values and return void:
  
               void *arg
!                      The arg passed to vmem_walk()

!                      The size of the segment
  
!      arg     An arbitrary argument passed to each call to func()
  
  DESCRIPTION
       vmem_walk() walks each segment in the arena vmp and applies func to each
       which matches typemask.
