  35   36  .Sh DESCRIPTION
  36   37  The
  37   38  .Fn Pissyscall
  38   39  function determines whether or not the instructions at
  39   40  .Fa addr
  40   41  in the process handle
  41   42  .Fa P
  42   43  corresponds to one of the architecture's system call instructions.
  43   44  .Pp
  44   45  the
  45   46  .Fn Pissyscall_prev
  46   47  function determines whether or not the instruction before
  47   48  .Fa addr
  48   49  in the process handle
  49   50  .Fa P
  50   51  corresponds to one of the architecture's system call instructions.
  51   52  If it does, and
  52   53  .Fa dst
  53   54  is a
  54   55  .Pf non- Dv NULL
  55   56  pointer, then the address of the system call instruction will be copied
  56   57  into the location pointed to by
  57   58  .Fa dst .
  58   59  .Sh RETURN VALUES
  59   60  Upon successful completion, the
  60   61  .Fn Pissyscall
  61   62  function returns
  62   63  .Sy non-zero
  63   64  if
  64   65  .Fa addr
  65   66  corresponds to a system call instruction.
  66   67  Otherwise,
  67   68  .Sy 0
  68   69  is returned.

  70   71  Upon successful completion, the

  74   75  if
  75   76  .Fa addr
  76   77  corresponds to a system call instruction and if
  77   78  .Fa dst
  78   79  is
