curlopt_verbose

CURLOPT_VERBOSE(3)					     curl_easy_setopt options						CURLOPT_VERBOSE(3)

NAME

       CURLOPT_VERBOSE - set verbose mode on/off

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 verbose information about its operations on this handle. Very useful for
       libcurl and/or protocol debugging and understanding. The verbose information  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, "http://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

RETURN VALUE

       Returns CURLE_OK
