CURLOPT_STREAM_WEIGHT(3)				     curl_easy_setopt options					  CURLOPT_STREAM_WEIGHT(3)

NAME
       CURLOPT_STREAM_WEIGHT - set numerical stream weight

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STREAM_WEIGHT, long weight);

DESCRIPTION
       Set the long weight to a number between 1 and 256.

       When  using  HTTP/2,  this  option sets the individual weight for this particular stream used by the easy handle. Setting and using weights
       only makes sense and is only usable when doing multiple streams over the same connections, which thus implies that you  use  CURLMOPT_PIPE-
       LINING(3).

       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

       Streams with the same parent should be allocated resources proportionally based on their weight. So if you have two streams going, stream A
       with  weight  16 and stream B with weight 32, stream B will get two thirds (32/48) of the available bandwidth (assuming the server can send
       off the data equally for both streams).

DEFAULT
       If nothing is set, the HTTP/2 protocol itself will use its own default which is 16.

PROTOCOLS
       HTTP/2
