curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period...

# NAME
|
|
|
|
CURLOPT_HTTPPOST - multipart formpost content
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
|
|
struct curl_httppost *formpost);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
**This option is deprecated.** Use CURLOPT_MIMEPOST(3) instead.
|
|
|
|
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* argument.
|
|
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_formadd(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), libcurl automatically sets
|
|
CURLOPT_NOBODY(3) to 0.
|

|
|
/* Fill in the file upload field. This makes libcurl load data from
|
|
the given file name when curl_easy_perform() is called. */
