CURLOPT_SASL_IR(3)  curl_easy_setopt options   CURLOPT_SASL_IR(3)

NAME

     CURLOPT_SASL_IR - enable sending 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 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

PROTOCOLS

     IMAP, POP3 and SMTP

EXAMPLE

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