.TH curl_formfree 3 "6 April 2001" "libcurl 7.7.1" "libcurl Manual"
.SH NAME
curl_formfree - free a previously build multipart/formdata HTTP POST chain
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "void curl_formfree(struct curl_httppost *" form);
.ad
.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 will make this function return
immediately with no action.
.SH EXAMPLE
.nf
/* 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);
.fi
.SH AVAILABILITY
Deprecated in 7.56.0.
.SH RETURN VALUE
None
