* 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
