设置网卡的混杂模式在VC中是用哪个函数？谢谢。我不想用winacap，在线等待

[raiky]

大家也可以谈谈winacap的用法

[cuiyxy]

socket(AF_INET, SOCK_RAW, IPPROTO_IP)

[cuiyxy]

#define AF_INET 2 /* internetwork: UDP, TCP, etc. */
#define SOCK_RAW 3 /* raw-protocol interface */
#define IPPROTO_IP 0 /* dummy for IP */

tocuiyxy(沧海鲨鱼)(★★★★★) ，你的意思是用原始套结口？我以前看到过类似API的直接的函数，可是资料找不到了，再搜索也没有了。
