| .TH CURLOPT_POSTFIELDSIZE_LARGE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options" |
| .SH NAME |
| CURLOPT_POSTFIELDSIZE_LARGE \- size of POST data pointed to |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE_LARGE, |
| curl_off_t size); |
| .SH DESCRIPTION |
| If you want to post 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, the library will use strlen() to get the size. |
| .SH DEFAULT |
| -1 |
| .SH PROTOCOLS |
| HTTP(S) |
| .SH EXAMPLE |
| .nf |
| CURL *curl = curl_easy_init(); |
| if(curl) { |
| const char *data = large_chunk; |
| curl_off_t length_of_data; /* set somehow */ |
| |
| curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); |
| |
| /* size of the POST data */ |
| curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, length_of_data); |
| |
| curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data); |
| |
| curl_easy_perform(curl); |
| } |

| .SH AVAILABILITY |
