获得通过‘的参数3的警告；pthread_create’；来自不兼容的指针类型[-Wincompatible指针类型]

我正在运行下面的代码，它工作得很好，但它仍然给出了一些我不理解的警告。有人能给我解释一下吗？谢谢

#include <stdio.h>
#include <pthread.h>

void* the_thread_func(double data_for_thread[]) {
  /* Do something here? */

        for(int i=0;i<3;i++){
    double sum = sum + data_for_thread[i];
    printf("The sum done by the_thread_func()  is = %f\n",sum);
   }

  return NULL;
}

int main() {
  printf("This is the main() function starting.\n");

  double data_for_thread[3];
  data_for_thread[0] = 5.7;
  data_for_thread[1] = 9.2;
  data_for_thread[2] = 1.6;

  /* Start thread. */
  pthread_t thread;
  printf("the main() function now calling pthread_create().\n");
  pthread_create(&thread, NULL, the_thread_func, data_for_thread);

  printf("This is the main() function after pthread_create()\n");

  /* Do something here? */

   for(int i=0;i<3;i++){
   double sum = sum + data_for_thread[i];
    printf("The sum done by main() is = %f\n",sum);
   }

  /* Wait for thread to finish. */
  printf("the main() function now calling pthread_join().\n");
  pthread_join(thread, NULL);

  return 0;
}

void*线程函数（线程[]的双数据）{
/*在这里做点什么*/
对于（int i=0；i，根据手册，需要提供具有此签名的函数：

void* (*start_routine)(void*)

但您正在传递一个函数，该函数在此处接受
double*
：

void* the_thread_func(double data_for_thread[]) // decays to double*

我认为您需要更改签名，并在函数内部强制转换
void*
，如下所示：

// accept void*
void* the_thread_func(void* vp) {
  /* Do something here? */

    double* data_for_thread = reinterpret_cast<double*>(vp); // cast here

    for(int i=0;i<3;i++){
        double sum = sum + data_for_thread[i];
        printf("The sum done by the_thread_func()  is = %f\n",sum);
    }

    return nullptr;
}

//接受无效*
void*线程函数（void*vp）{
/*在这里做点什么*/
double*data\u for\u thread=reinterpret\u cast（vp）；//在此处进行转换
