hardware information

[Dyutza]

How can I obtain some hardware information :motherboard Id ,etc from a C/C++ method?

[bluedragon]

U will need to read the information on a BIOS ROM

Different compilers have different headers for this one.

u will first need to create a handle that would fetch the information

I don't know much but it must be similar to fetching time from the BIOS

hi........

By default ANSI libraries wont provide to the capability to play with ur hardware........

the only solution is use operating system functions(like WIN32 api functions)

u can also retrive processor specific info using cpuid instruction........


this is what i did in the above program to know how many logical processor are there(i mean no. of cores)

__asm
{
mov eax,01h //01h for getting number of core present in the physical processor
cpuid
mov t,ebx
}
_tprintf(_T("\nNumber of logical processors(cores) : %d"),(t>>16)&0xff);

embed assembly in C is the workaround.................
