curl_free - Man Page

#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.
