.TH CURLOPT_TCP_NODELAY 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_TCP_NODELAY \- set the TCP_NODELAY option
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_NODELAY, long nodelay);
|
|
.SH DESCRIPTION
|
|
Pass a long specifying whether the TCP_NODELAY option is to be set or cleared
|
|
(1 = set, 0 = clear). The option is cleared by default. This will have no
|
|
effect after the connection has been established.
|
|
|
|
Setting this option will disable TCP's Nagle algorithm. The purpose of this
|
|
algorithm is to try to minimize the number of small packets on the network
|
|
(where "small packets" means TCP segments less than the Maximum Segment Size
|
|
(MSS) for the network).
|
|
|
|
Maximizing the amount of data sent per TCP segment is good because it
|
|
amortizes the overhead of the send. However, in some cases small segments may
|
|
need to be sent without delay. This is less efficient than sending larger
|
|
amounts of data at a time, and can contribute to congestion on the network if
|
|
overdone.
