NAME

6       CURLOPT_INFILESIZE_LARGE - size of the input file to send off
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
12                                 curl_off_t filesize);
13

DESCRIPTION

15       When uploading a file to a remote site, filesize should be used to tell
16       libcurl what the expected size of the input file is. This value must be
17       passed as a curl_off_t.
18
19       For uploading using SCP, this option or CURLOPT_INFILESIZE(3) is manda‐
20       tory.
21
22       To unset this value again, set it to -1.
23
24       When sending emails using SMTP, this command can be used to specify the
25       optional SIZE parameter for the MAIL FROM command.
26
27       This option does not limit how much data libcurl will actually send, as
28       that is controlled entirely by what  the  read  callback  returns,  but
29       telling one value and sending a different amount may lead to errors.
