.SH NAME
curl_formparse - add a section to a multipart/formdata HTTP POST
.SH SYNOPSIS
.B #include <curl/curl.h>

.BI "CURLcode curl_formparse(char *" string, "struct HttpPost **" firstitem,

.SH DESCRIPTION
curl_formparse() is used to append sections when building a multipart/formdata
HTTP POST. Append one section at a time until you've added all the sections
you want included and then you pass the
.I firstitem
pointer as parameter to CURLOPT_HTTPPOST.
.I lastitem
is set after each call and on repeated invokes it should be left as set to
allow repeated invokes to find the end of the list in a faster way.
.I string
must be a zero terminated string following the following syntax.
HTTP POST (sometimes refered to as rfc1867-style posts). Append one section at
a time until you've added all the sections you want included and then you pass
the \fI firstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP.
\fIlastitem\fP is set after each call and on repeated invokes it should be
left as set to allow repeated invokes to find the end of the list in a faster
way. \fIstring\fP must be a zero terminated string following the following
syntax.
The pointers \fIfirstitem\fP and \fIlastitem\fP point to, should both be
pointers to NULL in the first call to this function. All list-data will be
allocated by the function itself. You must call \fIcurl_formfree\fP after the
form has been done to free the resources again.
See example below.
