Please do. I hoped it could be determined simply via the existence of
environment variables (as it is possible with ssh-agent, environment

also don't know a command like 'ps' which returns running processes,
in order to check whether pageant is active.
  

PuTTY itself uses the following code:

int agent_exists(void)
{
    HWND hwnd;
    hwnd = FindWindow("Pageant", "Pageant");
    if (!hwnd)
	return FALSE;
    else
	return TRUE;
}
