+.TH CURLOPT_POST 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_POST \- request an HTTP POST
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POST, long post);
+.SH DESCRIPTION
+A parameter set to 1 tells libcurl to do a regular HTTP post. This will also
+make the library use a "Content-Type: application/x-www-form-urlencoded"
+header. (This is by far the most commonly used POST method).
+
+Use one of \fICURLOPT_POSTFIELDS(3)\fP or \fICURLOPT_COPYPOSTFIELDS(3)\fP
+options to specify what data to post and \fICURLOPT_POSTFIELDSIZE(3)\fP or
+\fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP to set the data size.
+
+Optionally, you can provide data to POST using the
+\fICURLOPT_READFUNCTION(3)\fP and \fICURLOPT_READDATA(3)\fP options but then
+you must make sure to not set \fICURLOPT_POSTFIELDS(3)\fP to anything but
+NULL. When providing data with a callback, you must transmit it using chunked
+transfer-encoding or you must set the size of the data with the
+\fICURLOPT_POSTFIELDSIZE(3)\fP or \fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP
+options. To enable chunked encoding, you simply pass in the appropriate
+Transfer-Encoding header, see the post-callback.c example.
+
+You can override the default POST Content-Type: header by setting your own
+with \fICURLOPT_HTTPHEADER(3)\fP.
+
+Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header.
+You can disable this header with \fICURLOPT_HTTPHEADER(3)\fP as usual.
+
+If you use POST to an HTTP 1.1 server, you can send data without knowing the
+size before starting the POST if you use chunked encoding. You enable this by
+adding a header like "Transfer-Encoding: chunked" with
+\fICURLOPT_HTTPHEADER(3)\fP. With HTTP 1.0 or without chunked transfer, you
+must specify the size in the request. (Since 7.66.0, libcurl will
+automatically use chunked encoding for POSTs if the size is unknown.)
+
+When setting \fICURLOPT_POST(3)\fP to 1, libcurl will automatically set
+\fICURLOPT_NOBODY(3)\fP and \fICURLOPT_HTTPGET(3)\fP to 0.
+
+If you issue a POST request and then want to make a HEAD or GET using the same
+re-used handle, you must explicitly set the new request type using
+\fICURLOPT_NOBODY(3)\fP or \fICURLOPT_HTTPGET(3)\fP or similar.
+.SH DEFAULT
+0, disabled
+.SH PROTOCOLS
+HTTP
+.SH EXAMPLE

+  curl_easy_setopt(curl, CURLOPT_POST, 1L);
+
+  /* set up the read callback with CURLOPT_READFUNCTION */
+
+  ret = curl_easy_perform(curl);
+
+  curl_easy_cleanup(curl);
