ctypes<type“exceptions.TypeError”>

Question

下面是我试图用python构建包装器的代码。

这是total.py文件（*c_t是长度为7的空数组（将在函数内部计算），t和rh是长度为Na的数组）

#double *initSeriesReversion(double *c_t, double *t, double *rh, int Na)
_inSR = _modi.initSeriesReversion
_inSR.argtypes = [ndpointer(ctypes.c_double * 7,   flags="C_CONTIGUOUS"),ndpointer(ctypes.c_double * 100, flags="C_CONTIGUOUS"),ndpointer(ctypes.c_double * 100, flags="C_CONTIGUOUS"),ctypes.c_int]
_inSR.restype = ctypes.POINTER(ctypes.c_double * 7)

还有Python的功能

def ini_SR(t, rh, Na):
    c_time = ctypes.POINTER(ctypes.c_double * 7)
    c_freq = _inSR(c_time,t,rh,Na)
    return c_time.value, c_freq

错误： 文件“”，第1行，在

File "total.py", line 28, in ini_SR

c_time = ctypes.POINTER(ctypes.c_double * 7)
ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: expected LP_c_double  instance instead of _ctypes.PyCPointerType
