| --- | --- | --- | --- |
| len | int | 输入输出的长度。 | 输入 |
| mean | double | mean参数。 | 输入 |
| sd | double | SD参数。 | 输入 |
| dst | double类型指针 | 指向结果的指针。 | 输出 |
| policy | VslPolicy类型指针 | 指向随机数生成器结构体指针。 | 输入 |

#### 示例

```
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include "kvsl.h"
int main()
{
    VslPolicy *policy;
    kml_vsl_init(&policy, LECUYER_CMRG, time(NULL));
    int len = 10;
    double *dst = (double *)malloc(sizeof(double) * len);
    int a = kml_vsl_rnorm(policy, BOX_MULLER, len, dst, 0, 1);
    for (int i = 0; i < len; i++) {
        printf("%f ", dst[i]);
    }
    printf("\n");
    kml_vsl_destroy(policy);
}
