Python 在ctypes中定义类型BT\u ADDR？

在尝试了一些简单的OS BT函数后，我怀疑我对

BT\u ADDR

的定义不正确。内容如下。我不熟悉ctypes，有人能给我一些提示吗？我的定义正确吗？我在python2.5上（是的，是的，硬件约束）

更新：我按照建议更新了代码，但在上述函数中仍然出现错误1168。我在下面的另一个函数上进行了尝试，效果很好

# int BthRemoteNameQuery(  BT_ADDR* pba,  unsigned int cBuffer,  unsigned int* pcRequired,  WCHAR* szString);
BthRemoteNameQuery = btdrt.BthRemoteNameQuery
BthRemoteNameQuery.argtypes = [ POINTER(w.BT_ADDR),  w.UINT , POINTER(w.UINT),  POINTER(w.WCHAR) ]
cBuffer = 256
pcRequired = pointer( c_uint() )
szString = ctypes.create_unicode_buffer( 256 )
rt = BthRemoteNameQuery( pba, cBuffer, pcRequired ,szString )
ec = GetLastError()
if rt != 0 :
    print( "Rt%s, Err%s" % (rt,ec)  )
else:
    print( 'returned length=', pcRequired.contents )
    print( 'string=', szString.value )
#>13
#>u'QR-386A-8B19'

BT_ADDR=ULONGLONG

。谢谢你的帮助。正是这个糟糕的功能不起作用。

# int BthRemoteNameQuery(  BT_ADDR* pba,  unsigned int cBuffer,  unsigned int* pcRequired,  WCHAR* szString);
BthRemoteNameQuery = btdrt.BthRemoteNameQuery
BthRemoteNameQuery.argtypes = [ POINTER(w.BT_ADDR),  w.UINT , POINTER(w.UINT),  POINTER(w.WCHAR) ]
cBuffer = 256
pcRequired = pointer( c_uint() )
szString = ctypes.create_unicode_buffer( 256 )
rt = BthRemoteNameQuery( pba, cBuffer, pcRequired ,szString )
ec = GetLastError()
if rt != 0 :
    print( "Rt%s, Err%s" % (rt,ec)  )
else:
    print( 'returned length=', pcRequired.contents )
    print( 'string=', szString.value )
#>13
#>u'QR-386A-8B19'
