curl_slist_free_all - free an entire curl_slist list

#include <curl/curl.h>
void curl_slist_free_all(struct curl_slist *list);

curl_slist_free_all() removes all traces of a previously built curl_slist linked list.

Passing in a NULL pointer in list will make this function return immediately with no action.

CURL *handle;
struct curl_slist *slist=NULL;
slist = curl_slist_append(slist, "X-libcurl: coolness");
if (slist == NULL)

return -1; curl_easy_setopt(handle, CURLOPT_HTTPHEADER, slist); curl_easy_perform(handle); curl_slist_free_all(slist); /* free the list again */

Always

Nothing.
