同样代码在windows下运行成功。

在windows下运行是正常的，可是在linux下运行结果是bind函数返回值是-1。errno值为0.google了很多资料，没发现我哪里有问题。大家帮帮忙看看吧！！

[解决办法]
确切的说，是进程的 CAP_NET_BIND_SERVICE 权限

C/C++ code

/* Allows binding to TCP/UDP sockets below 1024 *//* Allows binding to ATM VCIs below 32 */#define CAP_NET_BIND_SERVICE 10
[解决办法]
探讨

晕死，找到原因了。linux下不能使用1024以下的端口。nnd,这破问题折腾了我两天！！
