curl_free(3)		    Library Functions Manual		    curl_free(3)

NAME
     curl_free - reclaim memory that has been obtained through a libcurl call

SYNOPSIS
     #include <curl/curl.h>

     void curl_free(void *ptr);

DESCRIPTION
     curl_free	reclaims  memory  that has been obtained through a libcurl call.
     Use curl_free(3) instead of free() to avoid anomalies that can result  from
     differences in memory management between your application and libcurl.

     Passing  in  a  NULL  pointer in ptr makes this function return immediately
     with no action.

     int main(void)
     {

       }
     }
