        }
}


注：错误输出
sctpserv01.c: In function `main':
sctpserv01.c:16: error: storage size of 'sri' isn't known
sctpserv01.c:17: error: storage size of 'evnts' isn't known
sctpserv01.c:36: error: `SCTP_EVENTS' undeclared (first use in this function)
sctpserv01.c:36: error: (Each undeclared identifier is reported only once
sctpserv01.c:36: error: for each function it appears in.)

我通过一个SOCKET选项测试程序也得到了AS4不支持SCTP SOCKET选项,在netinet目录下也没有找到.sctp.h文件 大伙帮忙看看怎么样让AS4支持SCTP SOCKET选项呀先谢谢了.

似乎是缺少头文件。

你可以在include目录下grep找找看，或许是别的头文件。
