how to get current process ID and machine name in C++

In C#, it is straightforward to get the current process ID and machine name:

int processID = Process.GetCurrentProcess().Id;
string machineName = Environment.MachineName;

How can I retrieve them in native C++?

As you commented the platform is Windows 7, the WINAPI provides GetCurrentProcessId() and GetComputerName().

Simple example for GetComputerName():

const int BUF_SIZE = MAX_COMPUTERNAME_LENGTH + 1;
char buf[BUF_SIZE] = "";
DWORD size = BUF_SIZE;
if (GetComputerNameA(buf, &size)) // Explicitly calling ANSI version.
{ std::string computer_name(buf, size);
}
else
{ // Handle failure.
}

getpid() && gethostname() - use man to learn all about them...

#ifdef _WIN32 return GetCurrentProcessId();
#else return ::getpid();
#endif
