23 .TH CURLOPT_INFILESIZE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_INFILESIZE \- set size of the input file to send off
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long filesize);
31 When uploading a file to a remote site, \fIfilesize\fP should be used to tell
32 libcurl what the expected size of the input file is. This value must be passed
33 as a long. See also \fICURLOPT_INFILESIZE_LARGE(3)\fP for sending files larger
36 For uploading using SCP, this option or \fICURLOPT_INFILESIZE_LARGE(3)\fP is
39 To unset this value again, set it to -1.
41 When sending emails using SMTP, this command can be used to specify the
42 optional SIZE parameter for the MAIL FROM command.
44 This option does not limit how much data libcurl will actually send, as that
45 is controlled entirely by what the read callback returns, but telling one
46 value and sending a different amount may lead to errors.
