# NAME
|
||
|
|
|
||
|
|
CURLOPT_VERBOSE - verbose mode
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
