elegant way to do this, is to use

.TH curl_formadd 3 "19 August 2001" "libcurl 7.9" "libcurl Manual"
.SH NAME
curl_formadd - add a section to a multipart/formdata HTTP POST
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "CURLcode curl_formadd(struct HttpPost ** " firstitem,
.BI "struct HttpPost ** " lastitem, " ...);"
.ad
.SH DESCRIPTION
curl_formadd() is used to append sections when building a multipart/formdata
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 \fIfirstitem\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.
After \fIlastitem\fP follow the real arguments that constitute the
new section (if the following description confuses you jump directly
to the examples):
The first is always CURLFORM_COPYNAME followed by a string used for
the name of the section.
Afterwards one may use one of three arguments: CURLFORM_COPYCONTENTS,
CURLFORM_PTRCONTENTS, or CURLFORM_FILE. followed by a char or void
pointer (allowed for PTRCONTENTS).
The next argument may be CURLFORM_CONTENTTYPE if the
user wishes to specify one (for FILE if no type is given the library
tries to provide the correct one; for CONTENTS no Content-Type is sent
in this case)
For CURLFORM_PTRCONTENTS the user may also add CURLFORM_CONTENTSLENGTH
followed by the length as a long (if not given the library will use
strlen to determine the length; for COPYCONTENTS this is always done).
For CURLFORM_FILE the user may send multiple files in one section by
providing multiple CURLFORM_FILE arguments each followed by the filename
(and each FILE is allowed to have a CONTENTTYPE).
The last argument always is CURLFORM_END.
The pointers \fI*firstitem\fP and \fI*lastitem\fP should both be pointing 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 post has
been done to free the resources again.
This function will copy all input data except the data pointed to by
the argument after CURLFORM_PTRCONTENTS and keep its own
version of it allocated until you call \fIcurl_formfree\fP. When
you've passed the pointer to \fIcurl_easy_setopt\fP, you must not free
the list until after you've called \fIcurl_easy_cleanup\fP for the
curl handle. If you provide a pointer as an argument after
CURLFORM_PTRCONTENTS you must ensure that the pointer stays valid
until you call \fIcurl_form_free\fP and \fIcurl_easy_cleanup\fP.
See example below.
.SH RETURN VALUE
Returns non-zero if an error occurs.

* FormAdd()
*
* Stores a 'name=value' formpost parameter and builds the appropriate
* linked list.
*
* Has two principal functionalities: using files and byte arrays as
* post parts. Byte arrays are either copied or just the pointer is stored
* (as the user requests) while for files only the filename and not the
* content is stored.
*
* While you may have only one byte array for each name, multiple filenames
* are allowed (and because of this feature CURLFORM_END is needed after
* using CURLFORM_FILE).
*
* Examples:
*
* Simple name/value pair with copied contents:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_COPYCONTENTS, "value");
*
* name/value pair where only the content pointer is remembered:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_PTRCONTENTS, ptr, CURLFORM_CONTENTSLENGTH, 10);
* (if CURLFORM_CONTENTSLENGTH is missing strlen () is used)
*
* storing a filename (CONTENTTYPE is optional!):
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_FILE, "filename1", CURLFORM_CONTENTTYPE, "plain/text",
* CURLFORM_END);
*
* storing multiple filenames:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_FILE, "filename1", CURLFORM_FILE, "filename2", CURLFORM_END);
*
* Returns 0 on success, 1 if the first option is not CURLFORM_COPYNAME,
* 2 if AddHttpPost failes, and 3 if an unknown option is encountered
