Linux popen() alternative

[NiLSPACE]

Could this work?

AString GetOperationType()
{
   AString res = "unknown"
   #if defined (__WIN32__)
      res = "windows";
   #elif defined(__linux__)
      res = "linux";
   #elif defined(__APPLE__)
      res = "apple";
   #endif

   #ifdef __arm__
      res += " arm";
   #endif
   return res;
}

Just to get some basic information about the operation system.
