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. 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. .SH DEFAULT Unset .SH PROTOCOLS Many .SH EXAMPLE TODO .SH AVAILABILITY SMTP support added in 7.23.0 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_INFILESIZE_LARGE "(3), " CURLOPT_UPLOAD "(3), "
