+# NAME
+
+CURLOPT_PUT - make an HTTP PUT request
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PUT, long put);
+~~~
+
+# DESCRIPTION
+
+A parameter set to 1 tells the library to use HTTP PUT to transfer data. The
+data should be set with CURLOPT_READDATA(3) and
+CURLOPT_INFILESIZE(3).
+
+This option is **deprecated** since version 7.12.1. Use CURLOPT_UPLOAD(3).
+
+# DEFAULT
+
+0, disabled

+# EXAMPLE
+
+~~~c
+static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata)
+{
+  FILE *src = userdata;
+  /* copy as much data as possible into the 'ptr' buffer, but no more than
+     'size' * 'nmemb' bytes */
+  size_t retcode = fread(ptr, size, nmemb, src);
+
+  return retcode;
+}
+
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    FILE *src = fopen("local-file", "r");
+    curl_off_t fsize = 123456; /* set this to the size of the input file */
+
+    /* we want to use our own read function */
+    curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb);
+
+    /* enable PUT */
+    curl_easy_setopt(curl, CURLOPT_PUT, 1L);
+
+    /* specify target */
+    curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile");
+
+    /* now specify which pointer to pass to our callback */
+    curl_easy_setopt(curl, CURLOPT_READDATA, src);
+
+    /* Set the size of the file to upload */
+    curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);
+
+    /* Now run off and do what you have been told */
+    curl_easy_perform(curl);
+  }
+}
