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 CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/"); curl_easy_setopt(curl, CURLOPT_SASL_IR, 1L); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } AVAILABILITY Added in 7.31.0 RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
