NAME

6       CURLOPT_INFILESIZE - set size of the input file to send off

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long file‐
12       size);
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 long.  See  also  CURLOPT_INFILESIZE_LARGE(3)  for  sending
18       files larger than 2GB.
19
20       For  uploading using SCP, this option or CURLOPT_INFILESIZE_LARGE(3) is
21       mandatory.
22
23       To unset this value again, set it to -1.
24
25       When sending emails using SMTP, this command can be used to specify the
26       optional SIZE parameter for the MAIL FROM command.
27
28       This option does not limit how much data libcurl will actually send, as
29       that is controlled entirely by what  the  read  callback  returns,  but
30       telling one value and sending a different amount may lead to errors.
