curl_free - reclaim memory that has been obtained through a libcurl call
#include <curl/curl.h> void curl_free(void *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 makes this function return immediately with no action.
This functionality affects all supported protocols
int main(void) {
char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
} }
