NAME

       CURLOPT_VERBOSE - verbose mode

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. Useful for  libcurl  and/or  protocol  debugging  and
       understanding.  The  verbose  information  is  sent  to  stderr,  or  the  stream set with
       CURLOPT_STDERR(3).

       You hardly ever want this enabled in production use, you almost always want this used 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

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         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);
         }
       }
