  39  * File:                prinet.h
  40  * Description:
  41  *     Header file used to find the system header files for socket support[1].
  42  *     This file serves the following purposes:
  43  *     - A cross-platform, "get-everything" socket header file.  On
  44  *       Unix, socket support is scattered in several header files,
  45  *       while Windows and Mac have a "get-everything" socket header
  46  *       file[2].
  47  *     - NSPR needs the following macro definitions and function
  48  *       prototype declarations from these header files:
  49  *           AF_INET
  50  *           INADDR_ANY, INADDR_LOOPBACK, INADDR_BROADCAST
  51  *           ntohl(), ntohs(), htonl(), ntons().
  52  *       NSPR does not define its own versions of these macros and
  53  *       functions.  It simply uses the native versions, which have
  54  *       the same names on all supported platforms.
  55  *     This file is intended to be included by NSPR public header
  56  *     files, such as prio.h.  One should not include this file directly.
  57  *
  58  * Notes:
  59  *     1. This file should have been an internal header.  Please do not
  60  *        depend on it to pull in the system header files you need.
  61  *     2. WARNING: This file is no longer cross-platform as it is a no-op
  62  *        for WIN32!  See the comment in the WIN32 section for details.
