56 <p class="level0">Pass a curl_off_t as parameter. It contains the offset in number of bytes that you want the transfer to start from. Set this option to 0 to make the transfer start from the beginning (effectively disabling resume). For FTP, set this option to -1 to make the transfer start from the end of the target file (useful to continue an interrupted upload).
57 <p class="level0">When doing uploads with FTP, the resume position is where in the local/source file libcurl should try to resume the upload from and it will then append the source file to the remote target file. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
