.SH NAME
|
|
curl_formfree \- free a previously build multipart form post chain
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
void curl_formfree(struct curl_httppost *form);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
This function is deprecated. Do not use. See \fIcurl_mime_init(3)\fP instead!
|
|
|
|
curl_formfree() is used to clean up data previously built/appended with
|
|
\fIcurl_formadd(3)\fP. This must be called when the data has been used, which
|
|
typically means after \fIcurl_easy_perform(3)\fP has been called.
|
|
|
|
The pointer to free is the same pointer you passed to the
|
|
\fICURLOPT_HTTPPOST(3)\fP option, which is the \fIfirstitem\fP pointer from
|
|
the \fIcurl_formadd(3)\fP invoke(s).
|
|
|
|
\fBform\fP is the pointer as returned from a previous call to
|
|
\fIcurl_formadd(3)\fP and may be NULL.
|
|
|
|
Passing in a NULL pointer in \fIform\fP makes this function return immediately
|
|
with no action.
