我正在嘗試從WinPcap獲取有關已安裝的n/w設備的高級信息的示例。pcap_findalldevs_ex函數未定義
我甚至遵循包括WinPcap庫的說明,還是編譯器抱怨pcap_findalldevs_ex
在行if (pcap_findalldevs_ex(source, NULL, &alldevs, errbuf) == -1)
不確定
。
我的代碼:
#include "stdafx.h"
#include <stdio.h>
#include "pcap.h"
#include <winsock2.h>
#pragma comment(lib, "ws2_32")
// Function prototypes
void ifprint(pcap_if_t *d);
char *iptos(u_long in);
char* ip6tos(struct sockaddr *sockaddr, char *address, int addrlen);
int _tmain(int argc, _TCHAR* argv[])
{
pcap_if_t *alldevs;
pcap_if_t *d;
char errbuf[PCAP_ERRBUF_SIZE+1];
char source[PCAP_ERRBUF_SIZE+1];
printf("Enter the device you want to list:\n"
"rpcap:// ==> lists interfaces in the local machine\n"
"rpcap://hostname:port ==> lists interfaces in a remote machine\n"
" (rpcapd daemon must be up and running\n"
" and it must accept 'null' authentication)\n"
"file://foldername ==> lists all pcap files in the give folder\n\n"
"Enter your choice: ");
fgets(source, PCAP_ERRBUF_SIZE, stdin);
source[PCAP_ERRBUF_SIZE] = '\0';
/* Retrieve the interfaces list */
if (pcap_findalldevs_ex(source, NULL, &alldevs, errbuf) == -1)
{
fprintf(stderr,"Error in pcap_findalldevs: %s\n",errbuf);
exit(1);
}
/* Scan the list printing every entry */
for(d=alldevs;d;d=d->next)
{
ifprint(d);
}
pcap_freealldevs(alldevs);
return 1;
return 0;
}
/* Print all the available information on the given interface */
void ifprint(pcap_if_t *d)
{
//Code removed to reduce length and it contains no errors.
}
/* From tcptraceroute, convert a numeric IP address to a string */
#define IPTOSBUFFERS 12
char *iptos(u_long in)
{
//Code removed to reduce length
}
char* ip6tos(struct sockaddr *sockaddr, char *address, int addrlen)
{
//Code removed to reduce length
}
能有人指出我在正確的方向?
編輯:如果我在上面的代碼中使用pcap_findalldevs(&alldevs, errbuf)
,它會成功建立。所以我想連接到dll沒有問題。
編輯1:錯誤
錯誤C3861: 'pcap_findalldevs_ex':未找到
智能感知標識符:識別符 「pcap_findalldevs_ex」 未定義
感謝。
相同的答案爲我工作,加上我不得不引用32位庫而不是64位(WpdPack \ Lib \ x64),儘管我的64位操作系統 – 2017-11-18 17:14:25
