.TH CURLOPT_POSTFIELDSIZE 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_POSTFIELDSIZE \- size of POST data pointed to
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE, long size);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
If you want to post static data to the server without having libcurl do a
|
||
|
|
strlen() to measure the data size, this option must be used. When this option
|
||
|
|
is used you can post fully binary data, which otherwise is likely to fail. If
|
||
|
|
this size is set to -1, libcurl uses strlen() to get the size or relies on the
|
||
|
|
\fICURLOPT_READFUNCTION(3)\fP (if used) to signal the end of data.
|
||
|
|
|
||
|
|
If you post more than 2GB, use \fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP.
|
||
|
