CURLOPT_VERBOSE(3)	   Library Functions Manual	    CURLOPT_VERBOSE(3)

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 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).

       WARNING this may	show sensitive contents	from headers and data.

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
       Added in	curl 7.1

RETURN VALUE
       curl_easy_setopt(3) returns a CURLcode indicating success or error.

       CURLE_OK	(0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
