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

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.46.0

RETURN VALUE

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

CURLOPT_UPLOAD(3)					     curl_easy_setopt options						 CURLOPT_UPLOAD(3)

NAME

       CURLOPT_UPLOAD - enable data upload

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UPLOAD, long upload);

DESCRIPTION

       The  long  parameter  upload  set  to 1 tells the library to prepare for and perform an upload. The CURLOPT_READDATA(3) and CURLOPT_INFILE-
       SIZE(3) or CURLOPT_INFILESIZE_LARGE(3) options are also interesting for uploads. If the protocol is HTTP, uploading  means  using  the  PUT
       request unless you tell libcurl otherwise.

       Using  PUT  with  HTTP  1.1  implies the use of a "Expect: 100-continue" header.  You can disable this header with CURLOPT_HTTPHEADER(3) as
       usual.

       If you use PUT to a HTTP 1.1 server, you can upload data without knowing the size before starting the transfer if you use chunked encoding.
       You enable this by adding a header like "Transfer-Encoding: chunked" with CURLOPT_HTTPHEADER(3). With HTTP 1.0 or without chunked transfer,
       you must specify the size.

DEFAULT

       0, default is download

PROTOCOLS

       Most

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 /* we want to use our own read function */
	 curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback);

	 /* enable uploading */
	 curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

	 /* specify target */
	 curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile");

	 /* now specify which pointer to pass to our callback */
	 curl_easy_setopt(curl, CURLOPT_READDATA, hd_src);

	 /* Set the size of the file to upload */
	 curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);

	 /* Now run off and do what you've been told! */
	 curl_easy_perform(curl);
       }

AVAILABILITY

RETURN VALUE

       Returns CURLE_OK
