This book is meant to help the reader learn how to program in C. It contains a tutorial introduction to get new users started as soon as possible, separate chapters on each major feature, and a reference manual. Most of the treatment is based on reading, writing and revising examples, rather than on mere statements of rules. For the most part, the examples are complete, real programs rather than isolated fragments. All examples have been tested directly from the text, which is in machine-readable form. Besides showing how to make effective use of the language, we have also tried where possible to illustrate useful algorithms and principles of good style and sound design.

实现休眠功能很简单,只要在任意想要执行的地方执行如下给出的休眠函数SetPower()就行,其实休眠很简单,只需要API:SetSystemPowerState()就行,就如关机/注销/重启一样,只需要ExitWindowEx(),但这些API可以直接用在98下,却不能用在2000/XP中,因为这里牵涉到了用户权限,没有权限是不能进行这些操作的,所以,首先要取得权限,下面给出代码:-achieve dormancy function is very simple, as long as the implementation of the arbitrary want the local implementation of the dormancy is as follows function SetPower () on the trip, dormancy is very simple, just API : SetSystemPowerState () on the trip, as shutdown/cancellation/restart, only ExitWindowEx (), but these APIs can be directly used in 98, not in 2000/XP can use, because it involves a user privileges, no authority can carry out these operations, therefore, must first obtain authority code is given below :
