! 24:
! 25: .SH NAME
! 26: CURLOPT_RESUME_FROM \- set a point to resume transfer from
! 27: .SH SYNOPSIS
! 28: #include <curl/curl.h>
! 29:
! 30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
! 31: .SH DESCRIPTION
! 32: Pass a long as parameter. It contains the offset in number of bytes that you
! 33: want the transfer to start from. Set this option to 0 to make the transfer
! 34: start from the beginning (effectively disabling resume). For FTP, set this
! 35: option to -1 to make the transfer start from the end of the target file
! 36: (useful to continue an interrupted upload).
! 37:
! 38: When doing uploads with FTP, the resume position is where in the local/source
! 39: file libcurl should try to resume the upload from and it will then append the
! 40: source file to the remote target file.
! 41:
! 42: If you need to resume a transfer beyond the 2GB limit, use
! 43: \fICURLOPT_RESUME_FROM_LARGE(3)\fP instead.
