   3 NAME
   4      Pissyscall, Pissyscall_prev - determine if instructions are system call
   5      instructions

   7 SYNOPSIS
   8      Process Control Library (libproc, -lproc)

  11      int
  12      Pissyscall(struct ps_prochandle *P, uintptr_t addr);
  13 
  14      int
  15      Pissyscall_prev(struct ps_prochandle *P, uintptr_t addr, uintptr_t *dst);
  16 
  17 DESCRIPTION
  18      The Pissyscall() function determines whether or not the instructions at
  19      addr in the process handle P corresponds to one of the architecture's
  20      system call instructions.
  21 
  22      the Pissyscall_prev() function determines whether or not the instruction
  23      before addr in the process handle P corresponds to one of the
  24      architecture's system call instructions.  If it does, and dst is a
  25      non-NULL pointer, then the address of the system call instruction will be
  26      copied into the location pointed to by dst.
