CURLOPT_PIPEWAIT(3) curl_easy_setopt options CURLOPT_PIPEWAIT(3)
NAME
CURLOPT_PIPEWAIT - wait for pipelining/multiplexing
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PIPEWAIT, long wait);
DESCRIPTION
Set wait to 1L to tell libcurl to prefer to wait for a connection to
confirm or deny that it can do pipelining or multiplexing before con‐
tinuing.
When about to perform a new transfer that allows pipelining or multi‐
plexing, libcurl will check for existing connections to re-use and
pipeline on. If no such connection exists it will immediately continue
and create a fresh new connection to use.
By setting this option to 1 - and having CURLMOPT_PIPELINING(3) enabled
for the multi handle this transfer is associated with - libcurl will
instead wait for the connection to reveal if it is possible to pipe‐
line/multiplex on before it continues. This enables libcurl to much
better keep the number of connections to a minimum when using pipelin‐
ing or multiplexing protocols.
The effect thus becomes that with this option set, libcurl prefers to
wait and re-use an existing connection for pipelining rather than the
opposite: prefer to open a new connection rather than waiting.
The waiting time is as long as it takes for the connection to get up
and for libcurl to get the necessary response back that informs it
about its protocol and support level.
DEFAULT
0 (off)
PROTOCOLS
HTTP(S)
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {

}
AVAILABILITY
Added in 7.43.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
