How to convert inline assembler to .asm file

[togikan]

Hi all,

I'm having a problem converting an inline assembler function to .asm file. I need seperate inline assembler code because in x64 architecture doesn't have support for inline assembly. Here is the code(and attached as a txt file IsVM.txt at the bottom),

#include <windows.h>
#include <string>
#include <iostream>
#include <tlhelp32.h>

using namespace std;


int filter(int code)
{
if (code == EXCEPTION_PRIV_INSTRUCTION)
{
return EXCEPTION_EXECUTE_HANDLER;
}
else
{
return EXCEPTION_CONTINUE_SEARCH;
}
}

bool IsInsideVMWare(void)
{
bool rc = true;

__try
{
__asm
{
push edx
push ecx
push ebx

mov eax, 'VMXh'
mov ebx, 0 // any value but not the MAGIC VALUE
mov ecx, 10 // get VMWare version
mov edx, 'VX' // port number

in eax, dx // read port
// on return EAX returns the VERSION
cmp ebx, 'VMXh' // is it a reply from VMWare?
setz [rc] // set return value

pop ebx
pop ecx
pop edx
}
}
__except(filter(GetExceptionCode()))
{
rc = false;
}

return rc;
}

int main()
{
if(IsInsideVMWare())
cout << "You are in a VMware.." << endl;
else
cout << "You are in a native system.."<< endl;
system("PAUSE");
return 0;
}
Any idea how to convert and link to my cpp file? Thanks from now.

Can you not have IsInsideVMWare() in its own file an link to it by using a function prototype in the C++ file?

You just need the asm as a file in the project or you could pre-compile into a library that you add as a project linker dependency. You would still use the function prototype in the C++ code.
