.SH NAME
CURLOPT_VERBOSE \- verbose mode
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
.fi
.SH DESCRIPTION
Set the \fIonoff\fP parameter to 1 to make the library display a lot of
verbose information about its operations on this \fIhandle\fP. Useful for
libcurl and/or protocol debugging and understanding. The verbose information
is sent to stderr, or the stream set with \fICURLOPT_STDERR(3)\fP.

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
\fICURLOPT_DEBUGFUNCTION(3)\fP.
.SH DEFAULT
0, meaning disabled.
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
int main(void)
{
  CURL *curl = curl_easy_init();

    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);
  }
}
