我如何获得Cpu和Harddisk的温度...... [英] How Do I Get Cpu's And Harddisk's Temperature....

问题描述

。我试着通过wmi得到它...但是faild .......我用了C ...

.i try to get it by wmi ...but faild.......i used C...

#define _WIN32_WINNT 0x0400

{
	// result code from COM calls 
	HRESULT hr = 0;

	// release WMI COM interfaces

	CoUninitialize(); 

	SysFreeString(query); 
	SysFreeString(language); 
	SysFreeString(resource); 

	return;
}

推荐答案

您不能保证以这种方式（或任何其他方式）获得CPU或HDD温度 - 它完全取决于主板和硬盘驱动器的制造商是否提供了符合规范的硬件和驱动程序，并确实将其提供给系统。由于这不是强制性的，许多制造商根本不这样做，你得到的价值毫无意义。

You can't guarantee to get CPU or HDD temperatures in that way (or any other) - it depends entirely on whether the manufacturer of the motherboard and HDD have provided the hardware and drivers that conform to the spec and do provide it to the system at all. As this is not compulsory, many manufacturers do not do it at all, and the values you get are meaningless.
