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. Reported-by: Jay Satiro Bug: https://github.com/curl/curl/pull/15291#issuecomment-2410505100 Closes #15293

# NAME
|
|
|
|
CURLINFO_PROTOCOL - get the protocol used in the connection
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PROTOCOL, long *p);

|
~~~

|
|
# DESCRIPTION
|
|
|
|
This option is deprecated. We strongly recommend using
|
|
CURLINFO_SCHEME(3) instead, because this option cannot return all
|
|
possible protocols.
|
|
|
|
Pass a pointer to a long to receive the version used in the last http
|
|
connection. The returned value is set to one of the CURLPROTO_* values:
|
|
|
|
~~~c
|
|
CURLPROTO_DICT, CURLPROTO_FILE, CURLPROTO_FTP, CURLPROTO_FTPS,
|
|
CURLPROTO_GOPHER, CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_IMAP,
|
|
CURLPROTO_IMAPS, CURLPROTO_LDAP, CURLPROTO_LDAPS, CURLPROTO_POP3,
|
|
CURLPROTO_POP3S, CURLPROTO_RTMP, CURLPROTO_RTMPE, CURLPROTO_RTMPS,
|
|
CURLPROTO_RTMPT, CURLPROTO_RTMPTE, CURLPROTO_RTMPTS, CURLPROTO_RTSP,
|
|
CURLPROTO_SCP, CURLPROTO_SFTP, CURLPROTO_SMB, CURLPROTO_SMBS, CURLPROTO_SMTP,
|
|
CURLPROTO_SMTPS, CURLPROTO_TELNET, CURLPROTO_TFTP, CURLPROTO_MQTT
