CURLOPT_PUT(3) Library Functions Manual CURLOPT_PUT(3)

CURLOPT_PUT - make an HTTP PUT request

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PUT, long put);

A parameter set to 1 tells the library to use HTTP PUT to transfer data. The data should be set with CURLOPT_READDATA(3) and CURLOPT_INFILESIZE(3).

This option is deprecated since version 7.12.1. Use CURLOPT_UPLOAD(3).

    /* enable PUT */
    curl_easy_setopt(curl, CURLOPT_PUT, 1L);
    /* specify target */
    curl_easy_setopt(curl, CURLOPT_URL, "");
    /* now specify which pointer to pass to our callback */
    curl_easy_setopt(curl, CURLOPT_READDATA, 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 */

Deprecated since 7.12.1. Do not use.

Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
