Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLOPT_SASL_IR - send initial response in first packet
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_IR, long enable);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. If the value is 1, curl sends the initial response to the server
|
|
in the first authentication packet in order to reduce the number of ping pong
|
|
requests. Only applicable to the following supporting SASL authentication
|
|
mechanisms:
|
|
|
|
* Login
|
|
* Plain
|
|
* GSSAPI
|
|
* NTLM
|
|
* OAuth 2.0
|
|
|
|
Note: Whilst IMAP supports this option there is no need to explicitly set it,
|
|
as libcurl can determine the feature itself when the server supports the
|
|
SASL-IR CAPABILITY.
|
|
|
|
# DEFAULT
|
|
|
|
0
|
|
|
|
# EXAMPLE

curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_SASL_IR, 1L);
