+# NAME
+
+curl_formfree - free a previously build multipart form post chain
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+void curl_formfree(struct curl_httppost *form);
+~~~
+
+# DESCRIPTION
+
+This function is deprecated. Do not use. See curl_mime_init(3) instead.
+
+curl_formfree() is used to clean up data previously built/appended with
+curl_formadd(3). This must be called when the data has been used, which
+typically means after curl_easy_perform(3) has been called.
+
+The pointer to free is the same pointer you passed to the
+CURLOPT_HTTPPOST(3) option, which is the *firstitem* pointer from
+the curl_formadd(3) invoke(s).
+
+**form** is the pointer as returned from a previous call to
+curl_formadd(3) and may be NULL.
+
+Passing in a NULL pointer in *form* makes this function return immediately
+with no action.

+# EXAMPLE

+  CURL *curl = curl_easy_init();

+    struct curl_httppost *lastptr;
+
+    /* Fill in a file upload field */
+    curl_formadd(&formpost,
+                 &lastptr,
+                 CURLFORM_COPYNAME, "file",
+                 CURLFORM_FILE, "nice-image.jpg",
+                 CURLFORM_END);
+
+    curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
+
+    curl_easy_perform(curl);
+
+    /* then cleanup the formpost chain */
+    curl_formfree(formpost);
