winpcap编程使用

先安装winpcap,

再搜索下载WpdPack包，导入vc：工具->选项->目录:include file:E:\wujianhua\cpp\WpdPack\Include

library files:E:\wujianhua\cpp\WpdPack\Lib

然后编写代码：

#include <pcap.h>
#include <stdio.h>
#pragma comment(lib,"wpcap.lib")
#pragma comment(lib,"ws2_32.lib")


int main(){

	pcap_if_t *alldevs;
	pcap_if_t *d;
	int i=0;
	char errBuff[PCAP_ERRBUF_SIZE];
	if(pcap_findalldevs(&alldevs,errBuff)==-1){

		fprintf(stderr,"Error in pcap_findalldevs:%s\n",errBuff);
		return -1;
	}
	for(d=alldevs;d;d=d->next){
		printf("%d \t%s",++i,d->name);
		if(d->description){

			printf("(%s)\n",d->description);

		}else{
			printf("No description available!\b");
		}

	}
	if(i==0){
		
		printf("\n No Interface Found!\n Make Sure Wincap in installed!\n");
		return -1;
	}
	pcap_freealldevs(alldevs);


	return 0;
}
