/* $NetBSD: puffs.h,v 1.20 2007/01/09 18:15:08 pooka Exp $ */
add libpuffs - the userspace programming interface for puffs This work was initially started and completed for Google SoC 2005 and tweaked to work a bit better in the past few weeks. While being far from complete, it is functional enough to be able and stable to host a fairly general-purpose in-memory file system in userspace. Even so, puffs should be considered experimental and no binary compatibility for interfaces or crash-freedom or zero security implications should be relied upon just yet. The GSoC project was mentored by William Studenmund and the final review for the code was done by Christos.

checkpoint some experimental work-in-progress, namely: Add support for having multiple outstanding operations. This is done by exposing enough interfaces so that it is convenient to have the main event loop in the implementation itself and by providing a continuation framework for convinient blocking and rescheduling. works fine, but will undergo further cleanup & development
