+# NAME
+
+CURLOPT_RESUME_FROM - offset to resume transfer from
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
+~~~
+
+# DESCRIPTION
+
+Pass a long 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).
+
+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 then appends the
+source file to the remote target file.
+
+If you need to resume a transfer beyond the 2GB limit, use
+CURLOPT_RESUME_FROM_LARGE(3) instead.
+
+# DEFAULT
+
