import ctypes
w32 = ctypes.windll.kernel32

NORMAL_PRIORITY_CLASS = 0x00000020
IDLE_PRIORITY_CLASS = 0x00000040
HIGH_PRIORITY_CLASS = 0x00000080
REALTIME_PRIORITY_CLASS = 0x00000100

def ChangesProcessPriorityClass(new_class):
    proc_pseudohandle = w32.GetCurrentProcess()
    retv = w32.SetPriorityClass(proc_pseudohandle, new_class)
    if retv == 0:
        werrno = w32.GetLastError()
        raise EnvironmentError('SetPriorityClass -> %d' % (werrno,))
