curl_formfree - free a previously build multipart/formdata HTTP POST chain
#include <curl/curl.h> void curl_formfree(struct HttpPost *form);
curl_formfree() is used to clean up data previously built/appended with curl_formadd()/curl_formparse(). This must be called when the data has been used, which typi- cally means after the curl_easy_perform() has been called.
curl_formparse(3) [deprecated], curl_formadd(3)
libcurl 7.7.1 and earlier versions does not allow a NULL pointer to be used as argument.
