.TH CURLOPT_VERBOSE 3 "16 Jun 2014" libcurl libcurl
|
|
.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
|
|
All
|
