* bsd_epoll.h - Linux epoll.h compatible header
*
* Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> 2009
*
* description:
* This file makes any code that was compiled with <sys/epoll.h> header
* on Linux compile-able under FreeBSD and derivatives. It is meant to be
* used Together with bsd_epoll.c source file, to also be run-able.
*
* Example useage:
* Any code that was using epoll.h before can now do:
* #if defined(__linux__)
* # include <sys/epoll.h>
* #else
* # include "bsd_epoll.h"
* #endif
* Under FreeBSD the Makefile should add the bsd_epoll.c source file
*
* License:
* This header file is not under any license it has been long claimed
* and legally proven that Interfaces cannot be copyrighted.
* Now since this file only defines interfaces originally put forth
* by the Linux Kernel, they are not governed by any License.
* In anyway, Linus Trovalds, the originator of the Linux Kernel as
* Stated that the Linux Kernel's user-mode APIs are not copyrighted.
*
* This file was hand crafted by me based on Linux Kernel sources
* and GlibC's header epoll.h to be made code compatible with epoll.h
* Header on Linux.
*
* However, the implementation file bsd_epoll.c is copyrighted under
* the "New BSD License" so it can be included in the tirpc library
* project.
* But I fully expect that if you make any fixes/enhancements to
* bsd_epoll.c you shall send these changes to me for inclusion
* in the next version. (Or I'll hunt your dreams, and you will
* not have peace)
