+.TH CURLOPT_RESUME_FROM 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_RESUME_FROM \- set a point to resume transfer from
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
+.SH 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 will then append the
+source file to the remote target file.
+
+If you need to resume a transfer beyond the 2GB limit, use
+\fICURLOPT_RESUME_FROM_LARGE(3)\fP instead.
+.SH DEFAULT
+0, not used
+.SH PROTOCOLS
+HTTP, FTP, SFTP, FILE
+.SH EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com");
+
+  /* resume upload at byte index 200 */
+  curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L);
+
+  /* ask for upload */
+  curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
+
+  /* set total data amount to expect */
+  curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file);
+
+  /* Perform the request */
+  curl_easy_perform(curl);
