POSIX线程中多个线程可以共用一个属性吗？

[storylike]

我想创建好几个detached 线程，可以只设置一个attr对象，然后让他们共享么?比如这样：

pthread_t thread1,thread2,thread3;
pthread_attr_t thread_attr;

pthread_attr_init(&thread_attr);
pthread_attr_setdetachstate(&thread_attr,PTHREAD_CREATE_DETACHED);

pthread_craete(&thread1, &thread_attr, thread_function, (void *)message);
pthread_craete(&thread2, &thread_attr, thread_function, (void *)message);
pthread_craete(&thread3, &thread_attr, thread_function, (void *)message);

当然可以因为属性参数是const的。

#include <pthread.h>

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