# 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. |
