NAME

       CURLOPT_STREAM_DEPENDS_E - set stream this transfer depends on execlusively

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STREAM_DEPENDS_E, CURL *dephandle);

DESCRIPTION

       Pass  a	CURL * pointer in dephandle to identify the stream within the same connection that this stream is depending upon exclusively. That
       means it depends on it and sets the Exclusive bit.

       The spec says "Including a dependency expresses a preference to allocate resources to the identified stream rather than	to  the  dependent
       stream."

       Setting	a  dependency  with  the  exclusive flag for a reprioritized stream causes all the dependencies of the new parent stream to become
       dependent on the reprioritized stream.

       This option can be set during transfer.

       dephandle must not be the same as handle, that will cause this function to return an error. It must be another easy  handle,  and  it  also
       needs to be a handle of a transfer that will be sent over the same HTTP/2 connection for this option to have an actual effect.

DEFAULT

       NULL

PROTOCOLS

       HTTP/2

EXAMPLE

       TODO

AVAILABILITY

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
