CURLOPT_VERBOSE(3)

NAME
CURLOPT_VERBOSE - set verbose mode on/off

SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);

DESCRIPTION
Set the onoff parameter to 1 to make the library display a lot of verbose information about its operations on this handle. Very useful for libcurl and/or protocol debugging and understanding. The verbose information will be sent to stderr, or the stream set with CURLOPT_STDERR(3).

You hardly ever want this set in production use, you will almost always want this when you debug/report problems.

To also get all the protocol data sent and received, consider using the CURLOPT_DEBUGFUNCTION(3).

DEFAULT
0, meaning disabled.

PROTOCOLS
All

EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

  /* ask libcurl to show us the verbose output */
  curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

  /* Perform the request */
  curl_easy_perform(curl);
}

AVAILABILITY
Always

RETURN VALUE
Returns CURLE_OK
