# 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.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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);
|
|
}
|
|
}
