CURLOPT_INFILESIZE(3)

CURLOPT_INFILESIZE(3)curl_easy_setopt optionCURLOPT_INFILESIZE(3)

NAME

     CURLOPT_INFILESIZE - set size of the input file to send off

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle,  CURLOPT_INFILESIZE,
     long filesize);

DESCRIPTION

     When uploading a file to a remote site, filesize  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
     CURLOPT_INFILESIZE_LARGE(3)  for  sending  files larger than
     2GB.

     For    uploading    using    SCP,     this     option     or
     CURLOPT_INFILESIZE_LARGE(3) 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 com-
     mand.

     This option does not limit how much data libcurl will  actu-
     ally  send,  as that is controlled entirely by what the read
     callback returns, but telling one value and sending  a  dif-
     ferent amount may lead to errors.

DEFAULT

     Unset
