ccpuid:CPUID信息模块 V1.01版,支持GCC(兼容32位或64位的Windows/Linux)

作者:zyl910

  之前的ccpuid V1.00版(http://www.cnblogs.com/zyl910/archive/2012/07/11/ccpuid.html)只支持VC。

  现在的V1.01版支持GCC,不仅兼容32位/64位Linux下的GCC,还兼容Windows下的MinGW、MinGW-w64、TDM-GCC等。可以自由的编译为Windows下、或Linux下的程序。

一、更新说明

  主要的改进有——

1. 支持GCC。

2. 使用getcpuid/getcpuidex函数来获取CPUID信息。

3. 使用C99标准整数类型uint32_t,提高可移植性。

二、全部代码

2.1 头文件的全部代码
