CURLOPT_VERBOSE(3)         curl_easy_setopt options         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
       _STDERR&section=3">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
       _DEBUGFUNCTION&section=3">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
