CURLINFO_LOCAL_IP(3)




CURLINFO_LOCAL_IP(3)curl_easy_getinfo optionsCURLINFO_LOCAL_IP(3)


NAME

     CURLINFO_LOCAL_IP - get local IP address of last connection


SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_getinfo(CURL *handle,  CURLINFO_LOCAL_IP,
     char **ip);


DESCRIPTION

     Pass a pointer to a char pointer to receive the pointer to a
     zero-terminated  string  holding the IP address of the local
     end of most recent connection done with  this  curl  handle.
     This  string may be IPv6 when that is enabled. Note that you
     get a pointer to a memory area that will be re-used at  next
     request  so  you need to copy the string if you want to keep
     the information.

     The ip pointer will be NULL or pointing  to  private  memory
     you   MUST   NOT   free  -  it  gets  freed  when  you  call
     curl_easy_cleanup(3) on the corresponding CURL handle.


PROTOCOLS

EXAMPLE

     {
       char *ip;

       res = curl_easy_perform(curl);
       /* Check for errors */
       if((res == CURLE_OK) &&
          !curl_easy_getinfo(curl, CURLINFO_LOCAL_IP, &ip) && ip) {
         printf("Local IP: %s\n", ip);
       }

       /* always cleanup */
       curl_easy_cleanup(curl);
     }
