   4  *      rmt.h
   5  *
   6  *      Added routines to replace open(), close(), lseek(), ioctl(), etc.
   7  *      The preprocessor can be used to remap these the rmtopen(), etc
   8  *      thus minimizing source changes.
   9  *
  10  *      This file must be included before <sys/stat.h>, since it redefines
  11  *      stat to be rmtstat, so that struct stat xyzzy; declarations work
  12  *      properly.
