  24. .SH NAME
  25. CURLOPT_INFILESIZE_LARGE \- size of the input file to send off
  26. .SH SYNOPSIS
  27. .nf
  28. #include <curl/curl.h>
  29. CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
  30. curl_off_t filesize);
  31. .SH DESCRIPTION
  32. When uploading a file to a remote site, \fIfilesize\fP should be used to tell
  33. libcurl what the expected size of the input file is. This value must be passed
  34. as a \fBcurl_off_t\fP.
  35. For uploading using SCP, this option or \fICURLOPT_INFILESIZE(3)\fP is
  36. mandatory.
  37. To unset this value again, set it to -1.
  38. When sending emails using SMTP, this command can be used to specify the
  39. optional SIZE parameter for the MAIL FROM command.
  40. This option does not limit how much data libcurl will actually send, as that
  41. is controlled entirely by what the read callback returns, but telling one
  42. value and sending a different amount may lead to errors.
  43. .SH DEFAULT
  44. Unset
