curl_free - reclaim memory that has been obtained through a libcurl call #include <curl/curl.h> "void curl_free( char *" ptr " );" 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.

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