程序运行结束 在打印出“pthread_join”之后显示 段错误；//位置已经在程序里红色描出，前边的程序运行结果显示部分是正常的，最后就出现段错误了···

知道是越界，但是实在看不出是什么地方越界了，求大侠指点

pthread_create(&child_thread,NULL,sock_read(new_server_socket),NULL)
pthread_create(&child_thread,NULL,sock_read,(void *)&new_server_socket)

pthread_create(&child_thread,NULL,sock_read(new_server_socket),NULL)
pthread_create(&child_thread,NULL,sock_read,(void *)&new_server_socket)

编译的时候会产生警告：
12sslstest1.c: In function ‘sock_accept’:
12sslstest1.c:621: warning: passing argument 3 of ‘pthread_create’ from incompatible pointer type
/usr/include/pthread.h:227: note: expected ‘void * (*)(void *)’ but argument is of type ‘void * (*)(int)’

警告怎么去掉？

另外，在别函数调用这个new_server_socket的时候作为参数传递不过去，发数据和收数据发不出也收不到···
估计是这个new_server_socket的调用···不知道怎么解决？

参数传递改好了，只是程序只能运行一次，第二次的时候只显示：
段错误 (core dumped)

程序的结果也没有，是不是这个线程没有关闭？

[leihelin5201314]

搞定了，谢了

[NetBar_DJ]

如何搞定的？我目前也遇到段错的问题，查不出原因，很纠结呀

[fyjixian]

咋么搞定的。我也遇到同样的问题了。
