NAME

6       CURLOPT_VERBOSE - verbose mode

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
12

DESCRIPTION

14       Set  the onoff parameter to 1 to make the library display a lot of ver‐
15       bose information about  its  operations  on  this  handle.  Useful  for
16       libcurl and/or protocol debugging and understanding. The verbose infor‐
17       mation  will  be  sent  to  stderr,  or  the  stream  set   with   CUR‐
18       LOPT_STDERR(3).
19
20       You hardly ever want this set in production use, you will almost always
21       want this when you debug/report problems.
22
23       To also get all the protocol data sent and received, consider using the
24       CURLOPT_DEBUGFUNCTION(3).
