curl_free(3) Library Functions Manual curl_free(3)

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.

    /* it was set! */
