Fix new issues found by `proselint`. Also: - silence this technical warning: ``` :0: DeprecationWarning: /home/runner/.proselintrc was found instead of a JSON file. Rename to /home/runner/.proselintrc.json. ``` - fix an input filename. `proselints` fails now if an input file is missing.

# NAME
|
|
|
|
curl_formget - serialize a multipart form POST chain
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
int curl_formget(struct curl_httppost * form, void *userp,
|
|
curl_formget_callback append);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
The form API (including this function) is deprecated since libcurl 7.56.0.
|
|
|
|
curl_formget() serializes data previously built with curl_formadd(3). It
|
|
accepts a void pointer as second argument named *userp* which is passed as the
|
|
first argument to the curl_formget_callback function.
|
|
|
|
~~~c
|
|
typedef size_t (*curl_formget_callback)(void *userp, const char *buf,
|
|
size_t len);"
|
|
~~~
|
|
|
|
The curl_formget_callback is invoked 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 prevents
|
|
curl_formget(3) from working until you have performed the actual HTTP request.
|
|
This, because first then does libcurl known which actual read callback to use.
