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. The pointer to free is the same pointer you passed to the CURLOPT_HTTPPOST option, which is the firstitem pointer from the curl_formadd(3) invoke(s). form is the pointer as returned from a previous call to curl_formadd(3) and may be NULL. RETURN VALUE
None SEE ALSO
curl_formadd(3) libcurl 7.7.1 6 April 2001 curl_formfree(3)

NAME
CURLOPT_HTTPPOST - specify the multipart formpost content SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST, struct curl_httppost *formpost); DESCRIPTION
Tells libcurl you want a multipart/formdata HTTP POST to be made and you instruct what data to pass on to the server in the formpost argu- ment. Pass a pointer to a linked list of curl_httppost structs as parameter. The easiest way to create such a list, is to use curl_for- madd(3) as documented. The data in this list must remain intact as long as the curl transfer is alive and is using it. Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. You can disable this header with CURLOPT_HTTPHEADER(3). When setting CURLOPT_HTTPPOST(3), it will automatically set CURLOPT_NOBODY(3) to 0. DEFAULT
NULL PROTOCOLS
HTTP EXAMPLE
/* Fill in the file upload field. This makes libcurl load data from the given file name when curl_easy_perform() is called. */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "sendfile", CURLFORM_FILE, "postit2.c", CURLFORM_END); /* Fill in the filename field */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "filename", CURLFORM_COPYCONTENTS, "postit2.c", CURLFORM_END); /* Fill in the submit field too, even if this is rarely needed */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "submit", CURLFORM_COPYCONTENTS, "send", CURLFORM_END); AVAILABILITY
As long as HTTP is enabled RETURN VALUE
Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not. SEE ALSO
