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_free - reclaim memory that has been obtained through a libcurl call
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
void curl_free(void *ptr);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
curl_free reclaims memory that has been obtained through a libcurl call. Use
|
|
curl_free(3) instead of free() to avoid anomalies that can result from
|
|
differences in memory management between your application and libcurl.
|
|
|
|
Passing in a NULL pointer in *ptr* makes this function return immediately
|
|
with no action.
