NAME

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

SYNOPSIS

       #include <curl/curl.h>

       void curl_free(char *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  will make this function return immediately with no
       action.

EXAMPLE

         char *width = curl_getenv("COLUMNS");
         if(width) {
           /* it was set! */
           curl_free(width);
         }

AVAILABILITY

       Always

RETURN VALUE

       None
