Ansi C 参数给线程函数获取编译器错误

CreateThread 函数的参数参数出错：错误 C2440：'function'：无法从 'int (__cdecl *)(BIGVAR *)' 转换为 'LPTHREAD_START_ROUTINE' 对于每个线程，另一个用于读/写的变量列表和所有其他变量是只读。直接调用线程函数 thread(bigvar[2]); 工作正常。我必须做什么才能给每个线程一个指向每个变量列表的指针？

#define NUM_THREADS 5    
int thread(BIGVAR *bv);    
    
typedef struct typBIGVAR
{
 
 int var1;
 int var2[30];
 
 char var3];
 ...
 // many other variables
 
 }  BIGVAR;
 
 
int main ( int argc, char *argv[] )
{

  buffer = (char *) malloc(sizeof(BIGVAR) * NUM_THREADS);
  Mem = buffer;

  BIGVAR *bigvar[NUM_THREADS]; 
  
  unsigned long ThreadId[NUM_THREADS];
  
  int arrayThread[NUM_THREADS];
  
  
 
  for ( t=0; t<NUM_THREADS; t++ )
  {
    bigvar[t] = (BIGVAR *) Mem;
    Mem += sizeof(BIGVAR);
  }


  thread( bigvar[2] ); // this works fine 



  for ( t=0; t < NUM_THREADS; t++ )
  {
    

    bv = bigvar[t];
    arrayThread[t] = CreateThread(NULL, 0, &thread, bigvar[t], 0, &ThreadId[t]);
    if (arrayThread[t] == NULL)
    {
      printf("Create Thread %d get failed.\n",arrayThread[t]); 
    }
  
  }
 }
