Get RFLAGS using inline assembly

rflags.cpp

#include <iostream>
 
int main(void)
{
    unsigned long long var_RFLAGS = 0;
		 
    __asm__ (
	"pushfq;" // Put RFLAGS into stack
	"pop %%rax;" // Pop them in rax
	"mov %%rax, %0" :  :"m" (var_RFLAGS) // Retrieve them in a variable
    );
			 
    std::cout << std::hex << "RFLAGS : 0x" << var_RFLAGS << "\n";
				 
    return 0;
