c++生成动态dll,python调用该dll如何传参
这是dll链接

下面是c++函数代码
double* disp11(unsigned char* rev)
{
union gyro
{
char ch[4];
float f;
int si;
};
union gyro Gyrox[4];
unsigned short int data_temp1;
int i, j;
static double angleRT[16];
unsigned short int YearMonth; //年
unsigned short int Product_ID_T; //产品编号
i = 2;
Product_ID_T = rev[2] + rev[3] * 256; //产品编号
YearMonth = rev[4] + rev[5] * 256; //年
i = 11;
j = 0;
Gyrox[0].ch[0] = rev[i++]; //经度
Gyrox[0].ch[1] = rev[i++];
Gyrox[0].ch[2] = rev[i++];
Gyrox[0].ch[3] = rev[i++];
angleRT[0] = Gyrox[0].f;
i = 15;
j = 0;
Gyrox[0].ch[j++] = rev[i++]; //纬度
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
angleRT[1] = Gyrox[0].f;
i = 19;
j = 0;
Gyrox[0].ch[j++] = rev[i++]; //高度,m
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
angleRT[2] = Gyrox[0].f;
i = 23;
j = 0;
Gyrox[0].ch[j++] = rev[i++]; //航向
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
angleRT[3] = Gyrox[0].f;
i = 27;
j = 0;
Gyrox[0].ch[j++] = rev[i++]; //步数
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
Gyrox[0].ch[j++] = rev[i++];
angleRT[4] = Gyrox[0].f;
//步幅度,低字节
data_temp1 = rev[32] * 256 + rev[31];
angleRT[5] = (double)data_temp1;
angleRT[6] = (double)rev[33]; //卫星数
angleRT[7] = (double)rev[34]; //状态字1
angleRT[8] = (double)rev[35]; //状态字2
angleRT[9] = (double)Product_ID_T; //状态字2
angleRT[10] = (double)YearMonth; //年
angleRT[11] = (double)rev[6]; //月
angleRT[12] = (double)rev[7]; //日
angleRT[13] = (double)rev[8]; //时
angleRT[14] = (double)rev[9]; //分
angleRT[15] = (double)rev[10]; //秒
return angleRT;
}
这是我使用python调用的代码
from ctypes import *
dll = CDLL('./Dll1.dll')
print(dir(dll))
print(dll.disp11([0xAA,0x55,0xAD,0x02,0xBC,0x08,0x01,0x06,0x08,0x00,0x00,0x08,0x33,0xD6,0x42,0xF0,0x97,0xEF,0x41,0x24,0x18,0xB7,0x43,0xEF,0x69,0x56,0x43,0x00,0x00,0x50,0x41,0xA8,0x02,0x00,0x00,0x01,0xEF]))
返回应该是个数组,但是接受到却是一个整数,我该如何取出dll返回参数
