CURLOPT_SASL_IR(3) curl_easy_setopt options CURLOPT_SASL_IR(3)
NAME
CURLOPT_SASL_IR - send initial response in first packet
SYNOPSIS
#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 will send 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 support-
ing 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
PROTOCOLS
IMAP, POP3 and SMTP
EXAMPLE

ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
