Description: 用c语言编写串口程序
在当今,流行的编程软件种类繁多，它们编程方便、易于维护，但是在与硬
件直接打交道和编制系统软件时却束手无策，于是C语言就有了用武之地。C语言
作为汇编语言与高级语言之间的一种过渡语言，兼有汇编语言的高效和高级语言
的方便。
在通讯中，为了保证行运安全可靠，标准的串行口必须具有许多握手信号和
状态信息。这是因为通讯的各个计算机CPU速度不一样（这会导致“错帧”）以
及发送机发送数据速度比接收机接收速度快（这会导致“过冲”）。为解决这个
问题，我们采用一个简单的握手信号，即发送机每次仅发送半个字节（低4位）
的数据，而另外半个字节（高4位）则用来传送信息。我们可以对信息位（高4位）
进行如下简单的编码：
0H：发送的是新的半个字节数据
1H：重新发送上次传送错误的数据
2H：文件名结束
3H：文件结束
这样，每当发送机发送一个字节以后，就等待接受机发回送信号，这回送信号就
是发送机发送过来的那个字节。发送机接收到回送信号后，把它与刚发送的字节
相比较，如果相同，就发送新的半个字节，否则就重新发送。新数据与旧数据通
过信息位来区分。下面就是用C语言编写控制串行口的程序。
-Serial procedures in the preparation of today's popular programming software, and a large variety of their programming and easy to maintain, but to deal directly with the hardware and system software when compiled a loss, so there will be a C language battlefield. C language as the compilation and Advanced Language a transition between languages, both assembly language and the efficient high-level language convenience. In telecommunications, in order to ensure safe and reliable transport firms, the standard serial I must have shook hands with many signals and state information. This is because the various computer communications CPU speed is not the same (this would lead to "the wrong frame") and transmitter to send data faster than fast receiver to receive (this would lead t

Description: Cool Progress Bar is a regular progress bar, but
with some cool effects (ok, maybe I m exaggerating
a bit, but this was the first name that I came up
with!).
It was specially made for games (where a nice
progress bar when loading the game always looks
good, impresses the users and distracts them), but
you can use it anywhere else.
For now, all it supports is a gradation effect
between two colors you choose, and a background
color. But I plan to use a lot more effects, from
custom graphics to transition effects and masks.
Feel free to e-mail me your own suggestions.
Just make sure you dedicate at least one line to
me in the \"Thanks to\" section of your program/game
or credit me in any other way you see fit. That s

Description: This the string class you expected to find in STL, but didn t.
The design goal of this class is to make all the string handling functions from the standard C library available within a single C++ class, with the added bonus of automatic buffer allocation and deallocation.
The terse names of the original C functions have been preserved to ease the transition for C programmers. New functions have been given short but less cryptic names using the same style (one word, all lower case).
Most functions work as they do in the standard library or slightly better. Some examples:
1: The resulting string is always zero terminated.
2: All functions are thread safe in the sense that the class (but not an individual object) can be used by multiple threads concurrently.
3: Pre-conditions are tested using assert() which makes it possible to trap \"out of bounds\" errors in debug build, with no speed penalties in release build.
