在 C++ 中使用 pcap_findalldevs_ex 函数时出错
Error in use of the pcap_findalldevs_ex Function in c++
在此程序下方检索适配器列表并将其打印在屏幕上:
#include <stdio.h>
#include <pcap.h>
int main()
{
pcap_if_t *alldevs;
pcap_if_t *d;
int i=0;
char errbuf[PCAP_ERRBUF_SIZE];
if (pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL, &alldevs, errbuf) == -1)
{
fprintf(stderr,"Error in pcap_findalldevs_ex: %s/n", errbuf);
exit(1);
}
for(d= alldevs; d != NULL; d= d->next)
{
printf("%d. %s", ++i, d->name);
if (d->description)
printf(" (%s)/n", d->description);
else
printf(" (No description available)/n");
}
if (i == 0)
{
printf("/nNo interfaces found! Make sure WinPcap is installed./n");
return 0;
}
pcap_freealldevs(alldevs);
}
编译通过但报错:
每个人都有这些错误,在使用 pcap.h 时,转到下面 link 并下载 pcap,然后安装它:
