nbd_set_debug3

Usage

 #include <libnbd.h>
 int nbd_set_debug (
       struct nbd_handle *h, bool debug
     );

Overview

Set or clear the debug flag. When debugging is enabled, debugging messages from the library are printed to stderr, unless a debugging callback has been defined too (see nbd_set_debug_callback(3)) in which case they are sent to that function. This flag defaults to false on newly created handles, except if "LIBNBD_DEBUG=1" is set in the environment in which case it defaults to true.

Return value

If the call is successful the function returns 0.

Errors

On error -1 is returned.

Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in libnbd(3).

Version
