回复 2# greensnow

有include头文件啊！是书附带的代码，我没改过啊！谁能在cygwin或者RHEL下编译通过麻烦把gcc的命令行发一下给我学习。{:3_199:}

1. #include <stdio.h>
   
2. #include <stdlib.h>
   
3. #include <string.h>
   
4. #include <netdb.h>
   
5. #include "Practical.h"
   
6. 
   
7. int main(int argc, char *argv[]) {
   
8. 
   
9.   if (argc != 3) // Test for correct number of arguments
   
10.     DieWithUserMessage("Parameter(s)", "<Address/Name> <Port/Service>");
    
11. 
    
12.   char *addrString = argv[1];   // Server address/name
    
13.   char *portString = argv[2];   // Server port/service
    
14. 
    
15.   // Tell the system what kind(s) of address info we want
    
16.   struct addrinfo addrCriteria;                   // Criteria for address match
    
17.   memset(&addrCriteria, 0, sizeof(addrCriteria)); // Zero out structure
    
18.   addrCriteria.ai_family = AF_UNSPEC;             // Any address family
    
19.   addrCriteria.ai_socktype = SOCK_STREAM;         // Only stream sockets
    
20.   addrCriteria.ai_protocol = IPPROTO_TCP;         // Only TCP protocol
    
21. 
    
22.   // Get address(es) associated with the specified name/service
    
23.   struct addrinfo *addrList; // Holder for list of addresses returned
    
24.   // Modify servAddr contents to reference linked list of addresses
    
25.   int rtnVal = getaddrinfo(addrString, portString, &addrCriteria, &addrList);
    
26.   if (rtnVal != 0)
    
27.     DieWithUserMessage("getaddrinfo() failed", gai_strerror(rtnVal));
    
28. 
    
29.   // Display returned addresses
    
30.   for (struct addrinfo *addr = addrList; addr != NULL; addr = addr->ai_next) {
    
31.     PrintSocketAddress(addr->ai_addr, stdout);
    
32.     fputc('\n', stdout);
    
33.   }
    
34. 
    
35.   freeaddrinfo(addrList); // Free addrinfo allocated in getaddrinfo()
    
36. 
    
37.   exit(0);
    
38. }

可能IPv6的一些宏没有，去搜下getaddinfo，把它换掉试试
