<p class="level0">When uploading a file to a remote site, <span Class="emphasis">filesize</span> should be used to tell libcurl what the expected size of the input file is. This value must be passed as a <span Class="bold">curl_off_t</span>.
<p class="level0">For uploading using SCP, this option or <a Class="emphasis" href="./CURLOPT_INFILESIZE.html">CURLOPT_INFILESIZE</a> is mandatory.
<p class="level0">To unset this value again, set it to -1.
<p class="level0">When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.
<p class="level0">This option does not limit how much data libcurl will actually send, as that is controlled entirely by what the read callback returns, but telling one value and sending a different amount may lead to errors. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
