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 ver-
bose information about its operations on this handle. Useful for
libcurl and/or protocol debugging and understanding. The verbose infor-
mation will be sent to stderr, or the stream set with CUR-
LOPT_STDERR(3).
You hardly ever want this set in production use, you will almost always
want this 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
All
EXAMPLE
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
Always

Returns CURLE_OK
