32 Set the \fIonoff\fP parameter to 1 to make the library display a lot of
33 verbose information about its operations on this \fIhandle\fP. Very useful for
34 libcurl and/or protocol debugging and understanding. The verbose information
35 will be sent to stderr, or the stream set with \fICURLOPT_STDERR(3)\fP.
37 You hardly ever want this set in production use, you will almost always want
38 this when you debug/report problems.
40 To also get all the protocol data sent and received, consider using the
41 \fICURLOPT_DEBUGFUNCTION(3)\fP.
