.SH NAME
|
|
CURLOPT_STREAM_DEPENDS \- stream this transfer depends on
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STREAM_DEPENDS,
|
|
CURL *dephandle);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a CURL pointer in \fIdephandle\fP to identify the stream within the same
|
|
connection that this stream is depending upon. This option clears the
|
|
exclusive bit and is mutually exclusive to the \fICURLOPT_STREAM_DEPENDS_E(3)\fP
|
|
option.
|
|
|
|
The spec says "Including a dependency expresses a preference to allocate
|
|
resources to the identified stream rather than to the dependent stream."
|
|
|
|
This option can be set during transfer.
|
|
|
|
\fIdephandle\fP must not be the same as \fIhandle\fP, that makes this function return
|
|
an error. It must be another easy handle, and it also needs to be a handle of
|
|
a transfer that is about to be sent over the same HTTP/2 connection for this
|
|
option to have an actual effect.
|
|
.SH DEFAULT
|
|
NULL
|
|
.SH PROTOCOLS
|
|
This functionality affects http only
|
|

|
|
.nf

|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/one");
|
|
|
|
/* the second depends on the first */
|
|
curl_easy_setopt(curl2, CURLOPT_URL, "https://example.com/two");
|
|
curl_easy_setopt(curl2, CURLOPT_STREAM_DEPENDS, curl);
|
|
|
|
/* then add both to a multi handle and transfer them! */
|
|
}
|
|
}
|
