NAME

       curl_formfree - free a previously build multipart/formdata HTTP POST chain

SYNOPSIS

       #include <curl/curl.h>

       void curl_formfree(struct curl_httppost *form);

DESCRIPTION

       curl_formfree()	is  used to clean up data previously built/appended with curl_formadd(3). This must be called when the data has been used,
       which typically means after curl_easy_perform(3) has been called.

RETURN VALUE

       None

NAME

       curl_formget - serialize a previously built multipart/formdata HTTP POST chain

SYNOPSIS

       #include <curl/curl.h>

       void curl_formget(struct curl_httppost * form, void *userp,
			 curl_formget_callback append );

DESCRIPTION

       curl_formget()  is  used  to serialize data previously built/appended with curl_formadd(3). Accepts a void pointer as second argument named
       userp which will be passed as the first argument to the curl_formget_callback function.

       typedef size_t (*curl_formget_callback)(void *userp, const char *buf,  size_t len);

       The curl_formget_callback will be executed for each part of the HTTP POST chain. The character buffer passed to the callback  must  not	be
       freed. The callback should return the buffer length passed to it on success.

       If  the CURLFORM_STREAM option is used in the formpost, it will prevent curl_formget(3) from working until you've performed the actual HTTP
       request as only then will libcurl get the actual read callback to use!

RETURN VALUE

       0 means everything was ok, non-zero means an error occurred

EXAMPLE

	size_t print_httppost_callback(void *arg, const char *buf, size_t len)
	{
	  fwrite(buf, len, 1, stdout);
	  (*(size_t *) arg) += len;
	  return len;
	}

	size_t print_httppost(struct curl_httppost *post)
	{
	  size_t total_size = 0;
	  if(curl_formget(post, &total_size, print_httppost_callback)) {
	    return (size_t) -1;
	  }
	  return total_size;
	}
