怎么在c程序里实现移动光标
2009-6-1 14:18新警察请问、怎么在c程序里实现移动光标？〔是在用VC++开发的控制台程序里〕
是移动光标、不是移动鼠标的
就是在控制台里的、一闪一闪的那个光标
我想要做的是、输出几行字符串之后、把光标移动到第一行
我查了printf 函数的几个转义字符、没有能把光标向上移动的
在网上找到了GetCursorPos这样的函数、可是最后发现是关于鼠标的、而不是关于控制台的光标的
以前在TC里用的函数不能用了、现在俺无计可施了、高手救命啊、跪求！
ps ，是简单的控制台c 程序、不用MFC的

这个用Windows API的调用足够了。
CreateCaret.
DestroyCaret.
具体的用法查查msdn.
