CURLOPT_HTTP_TRANSFER_DECODING(3)

CURLOPT_HTTP_TRANSFER_DECODING3

Http transfer decoding control

Usage

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP_TRANSFER_DECODING,
                         long enabled);

Overview

Pass a long to tell libcurl how to act on transfer decoding. If set to zero, transfer decoding is disabled, if set to 1 it is enabled (default). libcurl does chunked transfer decoding by default unless this option is set to zero.

Default

1

Protocols

Examples

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;

    curl_easy_setopt(curl, CURLOPT_HTTP_TRANSFER_DECODING, 0L);
    result = curl_easy_perform(curl);
  }
}
