oracular (3) CURLOPT_VERBOSE.3.gz

Provided by: libcurl4-doc_8.9.1-2ubuntu2.2_all bug

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);
         }
       }

AVAILABILITY
