+.TH CURLOPT_POSTFIELDS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_POSTFIELDS \- specify data to POST to server
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDS, char *postdata);
+.SH DESCRIPTION
+Pass a char * as parameter, pointing to the full data to send in an HTTP POST
+operation. You must make sure that the data is formatted the way you want the
+server to receive it. libcurl will not convert or encode it for you in any
+way. For example, the web server may assume that this data is url-encoded.
+
+The data pointed to is NOT copied by the library: as a consequence, it must be
+preserved by the calling application until the associated transfer finishes.
+This behaviour can be changed (so libcurl does copy the data) by setting the
+\fICURLOPT_COPYPOSTFIELDS(3)\fP option.
+
+This POST is a normal application/x-www-form-urlencoded kind (and libcurl will
+set that Content-Type by default when this option is used), which is commonly
+used by HTML forms. Change Content-Type with \fICURLOPT_HTTPHEADER(3)\fP.
+
+You can use \fIcurl_easy_escape(3)\fP to url-encode your data, if necessary. It
+returns a pointer to an encoded string that can be passed as \fIpostdata\fP.
+
+Using \fICURLOPT_POSTFIELDS(3)\fP implies setting \fICURLOPT_POST(3)\fP to 1.
+
+If \fICURLOPT_POSTFIELDS(3)\fP is explicitly set to NULL then libcurl will get
+the POST data from the read callback. If you want to send a zero-byte POST set
+\fICURLOPT_POSTFIELDS(3)\fP to an empty string, or set \fICURLOPT_POST(3)\fP to
+1 and \fICURLOPT_POSTFIELDSIZE(3)\fP to 0.
+
+Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header,
+and libcurl will add that header automatically if the POST is either known to
+be larger than 1024 bytes or if the expected size is unknown. You can disable
+this header with \fICURLOPT_HTTPHEADER(3)\fP as usual.
+
+To make multipart/formdata posts (aka RFC2388-posts), check out the
+\fICURLOPT_HTTPPOST(3)\fP option combined with \fIcurl_formadd(3)\fP.
