小编Ais*_*nan的帖子

我创建了 pthread 如下：

void function1(void *s) {
start = (*(int *)s ;
}

pthread_t threads[numthreads];
int ids[numthreads];
for (i = 0; i < numthreads; i++) {
    ids[i] = i;
    int * p = &ids[i] ;
    pthread_create(&threads[i], NULL, function1, (void *)p);
}

但这给了我错误：

>> mpicc -o hprogram hprogram.c

      parameter of type 'void * _Nullable (* _Nonnull)(void * _Nullable)'
      [-Wincompatible-pointer-types]
