C 指针错误&；应为多线程‘；无效*（*）（无效*）&x2019；但参数的类型为‘；pthread_t’；

这段代码检查数独，用多线程。 编译后运行程序时： 分段故障（堆芯转储）

和错误：

su.c: In function ‘main’:
su.c:87:2: warning: passing argument 3 of ‘pthread_create’ makes pointer from integer without a cast [enabled by default]
In file included from su.c:4:0:
/usr/include/pthread.h:225:12: note: expected ‘void * (*)(void *)’ but argument is of type ‘pthread_t’
su.c:88:2: warning: passing argument 3 of ‘pthread_create’ makes pointer from integer without a cast [enabled by default]
In file included from su.c:4:0:

我的func是给定0参数：void*sub（）；

很抱歉，我的英语不好

这是

pthread\u create

的原型

int pthread_create(pthread_t *thread, const pthread_attr_t *attr,
                      void *(*start_routine) (void *), void *arg);

在这种情况下，第三个参数必须是返回void指针的函数，该函数接受一个参数void指针

因此，如上所述创建函数，然后将其传递给pthread_create的第三个参数

void * thr_fn2(void *arg)// your function must be like this.

然后使用该函数作为参数

void * my_row_function(void *param){ 
    Row * myrow = (Row*) param;
    //bla bla
}

int main(){
    Row * a_row= & row8outof9;
    pthread_create(&row,(const pthread_t*)NULL,
             my_row_function, a_row);
    return 0;
}

您需要作为第三个参数传递一个函数（返回void*并接受void*类型的1个参数），该函数将接收一个指针，您基本上必须将该指针转换回调用

pthread\u create

void * my_row_function(void *param){ 
    Row * myrow = (Row*) param;
    //bla bla
}

int main(){
    Row * a_row= & row8outof9;
    pthread_create(&row,(const pthread_t*)NULL,
             my_row_function, a_row);
    return 0;
}
