.TH CURLOPT_STREAM_WEIGHT 3 "13 Sep 2015" "libcurl 7.46.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_STREAM_WEIGHT \- set numerical stream priority
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STREAM_WEIGHT, long prio);
|
|
.SH DESCRIPTION
|
|
Set the long \fIprio\fP to a number between 1 and 256.
|
|
|
|
When using HTTP/2, this option can be used to set an individual weight for
|
|
this particular stream used by the easy \fIhandle\fP. Setting and using
|
|
weights really only makes sense and is only usable when doing multiple streams
|
|
over the same connections, which thus implies that you use
|
|
\fICURLMOPT_PIPELINING(3)\fP.
|
|
|
|
This option can be set during transfer and will then cause the updated weight
|
|
info get sent to the server the next time a HTTP/2 frame is sent to the
|
|
server.
|
|
|
|
See section 5.3 of RFC 7540 for protocol details:
|
|
https://httpwg.github.io/specs/rfc7540.html#StreamPriority
|
|
.SH DEFAULT
|
|
If nothing is set, the HTTP/2 protocol itself will use its own default which
|
|
is 16.
|
|
.SH PROTOCOLS
|
|
HTTP/2
|
|
.SH EXAMPLE
|
|

|
|
.SH AVAILABILITY
