  23         AROS_LHA(struct RastPort *, rp, A1),
  24
  25 /*  LOCATION */
  26         struct GfxBase *, GfxBase, 179, Graphics)

  28 /*  FUNCTION
  29         Frees the contents of a RastPort structure. The structure itself
  30         is not freed.
  31
  32     INPUTS
  33         rp - The RastPort which contents are to be freed.
  34
  35     RESULT
  36         None.
  37
  38     NOTES
  39         You can initialize the RastPort again via InitRastPort() but
  40         you must not use any other graphics function with it before
  41         that.
