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