.TH CURLOPT_INFILESIZE 3 "March 15 2024" libcurl
|
|
.SH NAME
|
|
CURLOPT_INFILESIZE \- size of the input file to send off
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long filesize);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
When uploading a file to a remote site, \fIfilesize\fP should be used to tell
|
|
libcurl what the expected size of the input file is. This value must be passed
|
|
as a long. See also \fICURLOPT_INFILESIZE_LARGE(3)\fP for sending files larger
|
|
than 2GB.
|
|
|
|
For uploading using SCP, this option or \fICURLOPT_INFILESIZE_LARGE(3)\fP is
|
|
mandatory.
|
|
|
|
To unset this value again, set it to \-1.
|
|
|
|
Using \fICURLOPT_UPLOAD(3)\fP to an HTTP/1.1 server and this value set to \-1, makes
|
|
libcurl do a chunked transfer\-encoded upload.
|
|
|
|
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 actually sends, as that is
|
|
controlled entirely by what the read callback returns, but telling one value
|
|
and sending a different amount may lead to errors.
