You can use strtol
function which works on regular C strings. It converts a string to a long using a specified base:
long l = strtol(str, NULL, 16);
details and good example: http://www.cplusplus.com/reference/clibrary/cstdlib/strtol/
#include <sstream>
#include <iostream>
int main()
{
std::string s("0xFFF000");
unsigned long value;
std::istringstream iss(s);
iss >> std::hex >> value;
std::cout << value << std::endl;
return 0;
}
