.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.
