   7  * File:        prinet.h
   8  * Description:
   9  *     Header file used to find the system header files for socket support[1].
  10  *     This file serves the following purposes:
  11  *     - A cross-platform, "get-everything" socket header file.  On
  12  *       Unix, socket support is scattered in several header files,
  13  *       while Windows has a "get-everything" socket header file[2].
  14  *     - NSPR needs the following macro definitions and function
  15  *       prototype declarations from these header files:
  16  *           AF_INET
  17  *           INADDR_ANY, INADDR_LOOPBACK, INADDR_BROADCAST
  18  *           ntohl(), ntohs(), htonl(), ntons().
  19  *       NSPR does not define its own versions of these macros and
  20  *       functions.  It simply uses the native versions, which have
  21  *       the same names on all supported platforms.
  22  *     This file is intended to be included by NSPR public header
  23  *     files, such as prio.h.  One should not include this file directly.
  24  *
  25  * Notes:
  26  *     1. This file should have been an internal header.  Please do not
  27  *        depend on it to pull in the system header files you need.
  28  *     2. WARNING: This file is no longer cross-platform as it is a no-op
  29  *        for WIN32!  See the comment in the WIN32 section for details.
