x SuSE Linux 13.1-RELEASE x x SuSE Linux 13.1-RELEASEx CURLOPT_UPLOAD(3) libcurl CURLOPT_UPLOAD(3) NAME CURLOPT_UPLOAD - 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_INFILESIZE(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 an HTTP 1.1 server, you can upload data without know- ing the size before starting the transfer. The library enables this by adding a header "Transfer-Encoding: chunked". With HTTP 1.0 or if you prefer not to use chunked transfer, you must specify the size of the data with CURLOPT_INFILESIZE(3) or CURLOPT_INFILESIZE_LARGE(3). 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 have been told! */ curl_easy_perform(curl); } AVAILABILITY Always RETURN VALUE Returns CURLE_OK SEE ALSO CURLOPT_PUT(3), CURLOPT_READFUNCTION(3), CURLOPT_INFILESIZE_LARGE(3) ibcurl 8.4.0 September 26, 2023 CURLOPT_UPLOAD(3)
