(未测试)应该可以。第四个参数的类型为 POINTER(c_double)
。 C的 double returnarray [6]
类型的等效项为 c_double * 6
,该类型的实例为 returnarray =(c_double * 6)()
。另外,如果您声明了参数类型,则无需包装输入参数,例如 int(0)
;。传递 0
很好:
This (untested) should work. The 4th parameter is type POINTER(c_double)
. The equivalent of C's double returnarray[6]
type is c_double * 6
and an instance of that type is returnarray= (c_double * 6)()
. Also, if you've declared the argument types you don't need to wrap the input parameters such as int(0)
; passing 0
is fine:
dll = windll.LoadLibrary(# file path)
# retype the args for swe_calc_ut
py_swe_calc_ut = dll.swe_calc_ut
py_swe_calc_ut.argtypes = [c_double, c_int, c_int, POINTER(c_double), c_char_p]
py_swe_calc_ut.restype = None
tdj = 1.5 # some value
returnarray = (c_double * 6)()
errorstring = create_string_buffer(126)
py_swe_calc_ut(tjd, 0, 64*1024, returnarray, errorstring)
