Linux 上的 SO_REUSEPORT [英] SO_REUSEPORT on linux

问题描述

I want to know if SO_REUSEPORT option is enabled in LINUX 2.6 or not ??

If I try to use it and compile my code I get following error

01.c:72: error: `SO_REUSEPORT' undeclared (first use in this function)
01.c:72: error: (Each undeclared identifier is reported only once
01.c:72: error: for each function it appears in.)

Using the above option I guess I can bind two different sockets to same IPADRESS and PORT NUMBER

解决方案

this options was done in kernel 3.9, see this git commit
