CURLOPT_INFILESIZE_LARGE man page

## NAME

CURLOPT_INFILESIZE_LARGE - set size of the input file to send off

## SYNOPSIS

    #include <curl/curl.h>
     CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
                               curl_off_t filesize);

## DESCRIPTION

When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value must be passed as a curl_off_t.

For uploading using SCP, this option or CURLOPT_INFILESIZE is mandatory.

To unset this value again, set it to -1.

When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.

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.

## DEFAULT

Unset

## PROTOCOLS

Many

## EXAMPLE

TODO

## AVAILABILITY

SMTP support added in 7.23.0

## RETURN VALUE

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