| 23 .TH CURLOPT_TCP_NODELAY 3 "30 Jun 2016" "libcurl 7.50.0" "curl_easy_setopt options" | |
| 24 .SH NAME | |
| 25 CURLOPT_TCP_NODELAY \- set the TCP_NODELAY option | |
| 26 .SH SYNOPSIS | |
| 27 #include <curl/curl.h> | |
| 28 | |
| 29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_NODELAY, long nodelay); | |
| 30 .SH DESCRIPTION | |
| 31 Pass a long specifying whether the TCP_NODELAY option is to be set or cleared | |
| 32 (1L = set, 0 = clear). The option is set by default. This will have no effect | |
| 33 after the connection has been established. | |
| 34 | |
| 35 Setting this option to 1L will disable TCP's Nagle algorithm on this | |
| 36 connection. The purpose of this algorithm is to try to minimize the number of | |
| 37 small packets on the network (where "small packets" means TCP segments less | |
| 38 than the Maximum Segment Size (MSS) for the network). | |
| 39 | |
| 40 Maximizing the amount of data sent per TCP segment is good because it | |
| 41 amortizes the overhead of the send. However, in some cases small segments may | |
| 42 need to be sent without delay. This is less efficient than sending larger | |
| 43 amounts of data at a time, and can contribute to congestion on the network if | |
| 44 overdone. | |
| 45 .SH DEFAULT | |
| 46 1 | |
| 47 .SH PROTOCOLS | |
| 48 All | |
| 49 .SH EXAMPLE | |
| 50 .nf | |
| 51 CURL *curl = curl_easy_init(); | |
| 52 if(curl) { | |
| 53 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); | |
| 54 /* disable Nagle */ | |
| 55 curl_easy_setopt(curl, CURLOPT_TCP_NODELAY, 0); | |
| 56 curl_easy_perform(curl); | |
| 57 } | |
| 58 .fi | |
| 59 .SH AVAILABILITY | |
| 60 Always. The default was changed to 1 from 0 in 7.50.2. | |
| 61 .SH RETURN VALUE | |
| 62 Returns CURLE_OK | |
